Karuna Tiwari Greetings!
The 2023-06-01-preview
API will remain supported at this time.
But if we upgrade the version to latest 2024-03-01-preview or 2024-02-15-preview, we get a 'Resource not Found' error.
Could you confirm how exactly are you upgrading?
Regarding resource not found error for 2024-03-01-preview or 2024-02-15-preview, please see this PR and check for the naming conventions and be sure to merge the latest API version update into your own application code and redeploy.
These changes will work for both 2024-02-15-preview and 2024-03-01-preview.
Do let me know if that works or have any further queries.
