The error you're encountering, blockBlob download failed, during Snowflake Git integration usually indicates an issue with downloading files from your Azure DevOps repository, possibly linked to either permissions, configuration, or network problems.

• Check Permissions:

Ensure Snowflake has read access to the Azure DevOps repository.

• Verify Git Integration:

Double-check repository URL, branch, and path in Snowflake’s Git settings.

• Network Access:

Ensure there are no firewall or network issues blocking access between Snowflake and Azure DevOps.

• Reconnect Integration:

Disconnect and reconnect the Git integration in Snowflake, then fetch the latest branch.

• Blob Storage Access (if applicable):

Ensure Snowflake has correct permissions to Azure Blob Storage if files are stored there.
