Troubleshooting Guide

This section outlines known issues encountered during setup or usage of LakeFusion, along with steps to resolve them.

1. Error Accessing the Match Maven Screen

Issue:
Users encounter an error when attempting to access the Match Maven screen within the LakeFusion UI.

Cause:
This error typically occurs because the Databricks Vector Search feature is not enabled in the user's workspace. The API call to the Vector Search endpoint fails as a result.

Resolution:

  • Databricks Vector Search is currently in Public Preview (as of early 2025).

  • It may not be enabled by default in your workspace, particularly if you're on an older or enterprise workspace setup, or if Unity Catalog is not configured.

To resolve the issue:

  1. Reach out to your Databricks account representative or support team.

  2. Request activation of the Vector Search feature in your workspace.

​
Once enabled, you should be able to access the Match Maven screen without errors.

2. Region Not Supported During Provisioning

Issue:
Users receive the following error message during deployment:
"Provisioning in requested region is not supported."

Cause:
The selected region is not supported for the deployment configuration.

Resolution:

Choose a different region in the setup form during deployment.


Verification:

To verify the error through Azure logs:

  1. Go to the Azure Portal.

  2. Search for Resource Groups.

  1. Open your Resource Group

  1. Click on the corresponding Container Group.

  1. In the left-hand menu, expand Settings and select Containers.

  1. Open the Logs tab.

  1. If you see the following message in the log console {"code":"ProvisionNotSupportedForRegion","message":"Provisioning in requested region is not supported."}}

This confirms the issue is region-related. Select a supported region in the deployment form and retry.
