Known issues and workarounds​

Known IssueWorkaround
MLOps error when upgrading to Helm 0.16.0.Delete the <prefix-env>-mlops-environment-admin role before upgrading the Helm release:

sh kubectl -n mlops delete role/<prefix-env>-mlops-environment-admin
When manually setting the SSL_CERT_FILE and REQUESTS_CA_BUNDLE to /etc/ssl/certs/appstore-ca-bundle.crt (where all Wave apps set the CA cert), the Wave apps fail to install packages from PyPi.1. Run the following commands (this only needs to be done once per user. If done before, go to step 2):

a. Run:
sh docker run -it --rm --entrypoint /bin/sh us-docker.pkg.dev/vorvan/dev/h2oai-appstore-runtimecpu39:v0.36.4

b. Extract the certificate:
sh cat /etc/ssl/certs/ca-certificates.crt

c. Copy the contents and paste them into your ca-chain.crt.

2. Modify terraform/modules/applications/appstore/resources/google-values.yaml and reapply Terraform:

At line 43, add:
yaml %{~ if enable_private_ca_certs ~} caCertificateAppMountpoints: - /etc/ssl/certs/appstore-ca-bundle.crt - /etc/ssl/certs/ca-certificates.crt %{~ endif ~}

At line 222, add:
yaml %{~ if enable_private_ca_certs ~} - name: REQUESTS_CA_BUNDLE value: /etc/ssl/certs/ca-certificates.crt - name: SSL_CERT_FILE value: /etc/ssl/certs/ca-certificates.crt %{~ endif ~}
resource "google_secret_manager_secret" "mlapi_admin_password" and resource "google_secret_manager_secret_version" "mlapi_admin_password" are being created even when MLAPI Postgres is disabled.Update the create_mlapi_postgres flag in terraform/modules/gcp-dependencies/secret-manager.tf file (line 113 and 122) to the following condition:

hcl count = var.enable_secret_management && var.create_mlapi_postgres ? 1 : 0
Execution error when H2O Drive storage location variable is empty.Update terraform/modules/applications/gcp/locals.tf line 75 to the following:

hcl drive_storage_location = local.install_drive && var.drive_storage_location == "" ? data.google_storage_bucket.drive_container[0].location : var.drive_storage_location
There is no flag controlling the deployment_server database in terraform/modules/azure-dependencies/postgres_common_server.tf, so it is always created.Control the count manually or add this line (along with associated variables) to terraform/modules/applications/azure/variables.tf:

hcl count = var.run_create_db_and_user_script && var.external_postgres_deployment ? 1 : 0
When using the default MLOps deployment database created in azure-dependencies, the connection string is not populated correctly in the Kubernetes secret when installing mlops_helm.
This bug will only affect you if you create the databases through the Terraform installer.		Set the variables like mlops_deployment_db_address, mlops_deployment_db_name, etc., in terraform/modules/applications/azure.
When creating a deployment with the H2O Driverless AI Python Pipeline > Python Pipeline Scorer (DAI 1.10.7) in MLOps, the deployment pod fails with a Read-only file system: './tmp' error.Add the following to terraform/modules/applications/mlops-helm/resources/values.yaml at line 483:

Known issues and workarounds​

Known IssueWorkaround
When adding a file in Edit in Page View on H2O Document AI, the changes are not reflected on the Annotation Set list view.Refresh the page or click on another menu item (e.g. Document Sets) and
click back to annotation sets to see the updated number of pages.
When adding a file in Edit in Page View of an Annotation Set on H2O Document AI, it only supports image files. JSON files are not supported.Export the .pdf as a .jpg or .png and then add the file in edit page view.
After adding a file in Edit in Page View in the H2O Document AI publisher, if you leave edit in page view and then return to it again, the added file does not show up.Currently, no workaround available.
H2O Document AI pipeline creation fails on OpenShift when Linkerd is enabled.Exclude port 443 in document-ai-viewer namespace by annotating the namespace with 
config.linkerd.io/skip-outbound-ports: "443"
When using the Edit in Page View in the H2O Document AI publisher on the Apple Safari browser, the first label gets pre-populated resulting in the bounding box not being labeled as such.This issue does not occur when using Google Chrome.
Keycloak pods are not started by default when Linkerd is enabled by default.Keycloak pods are not injected to the Linkerd proxy for fresh installs even
though the Linkerd inject is enabled for the Keycloak namespace.
Restart the Keycloak pod after Linkerd pods come up in your Kubernetes cluster.
Variable gcp_region does not take affect for Kubernetes module installation.Add the following line in the file terraform/templates/kubernetes/main.tf,
under the module kubernetes_gcp{}. 
gcp_region = var.gcp_region
H2O Document AI proxy ships a network policy that blocks Egress traffic from post-processor pods. If your H2O AI Hybrid Cloud environment has Calico (or any CNI that enforces NetworkPolicy) + Linkerd enabled, the custom post processor pod fails after 120 seconds.If Linkerd is enabled, delete the networkpolicy in the
document-ai-scorer namespace after deployment.
Alternatively, you can also update the helm flag as follows. 
publish: 
networkPolicy: 
enabled: false
or
publish.networkPolicy.enabled=false
Unable to start H2O-3 in H2O AI Engine Manager when Linkerd is enabled by default.Disable Linkerd in H2O AI Engine Manager.
hcl linkerd_aiem_manager_annotations = { "linkerd.io/inject" = "disabled" }
H2O Driverless AI versions prior to v1.10.4.2 are inaccessible post-migration to private CAUpgrade H2O Driverless AI to v1.10.4.2 or a later version.
Permission issue in container resulted in Minio job that creates the Minio bucket failing on OpenShift.Create the buckets manually
The Enterprise Steam setup fails to run on airgapped environments as it requires creating a virtual environment and installing the Steam client.Configure Enterprise Steam on the UI manually.
The mlops_helm installation uses the wrong code to get db_admin_password/db_name/db_address for deployment of PostgreSQL Server.Update lines 54, 59 and 129 on the modules/applications/aws/data.tf file
to use var.external_postgres_deployment variable instead of var.external_postgres.
When running the deployments-tf-scale-down.sh or deployments-tf-scale-up.sh scripts during the upgrade, the script fails in the middle.Replace lines 24-26 of the relevant script with the following code snippet:
bash optional_components=( 'ui' 'externalregistry' 'prometheus-server' ) for oc in "${optional_components[@]}"; do if kubectl -n "$ns" get deployment "${prefix}-${oc}" >/dev/null 2>&1; then components+=("${oc}") fi done
The variable name used to define the H2O MLOps monitoring db name is mlops_monitoring_db but in dependencies it is named as mlops_monitoring_db_name.
The same variable name should be used to avoid any issues.		Include both variables in the config.tfvars file to avoid any issues
Restoring the external-registry-adapter fails.Update the following variables with the following values in templates and modules:
  • mlops_monitoring_db_username = "mlops_model_monitoring"
  • mlops_deployment_db_username = "deployment_server"
  • mlops_db_username = "h2oai_storage"
  • mlops_deployment_db_name = "deployment_server"
  • mlops_monitoring_db = "mlops_model_monitoring"
  • mlops_db_name = "h2oai_storage"
The image pull secret does not get created in the feature-store-redis namespace due to the namespace variable being empty.Include featurestore_redis_namespace = "feature-store-redis" in the config.tfvars file or update templates & modules to set feature-store-redis to the variable.

Optional components​

Optional components of HAIC are provided to customers as needed based on your specific requirements. If you have any of the following components, note the following upgrades.

  • H2O Document AI v0.6.2

New features​

  • Added the ability to update or add new templates in H2O Document AI

Bug fixes​

  • Fixed an issue in H2O Document AI where the logic used to pull the feature store web proxy image did not work if the image registry is empty.
  • Made an improvement to include input_dir content in the request going to the custom post-processor deployment.

Known issues and workarounds​

Known IssueWorkaround
Deploying an H2O Document AI pipeline with a long name fails.To avoid this issue, use pipeline names that are as short as possible (preferably 3-4 characters) in H2O Document AI. In a future release, the issue will be fixed by decoupling the pipeline resource names from the name provided by the customer.
After publishing a pipeline using a model trained on one file on H2O Document AI Viewer, the document will show zero results.This has more to do with the quality of the model trained. If you try to score with the same file used for training then it will probably, though not guaranteed, find at least one entity.
Additionally, it also depends on how the bounding box was created. If the bounding box is very small or useless, then it may result in this situation.
