Hi there Kirankumar Bharsadiya
Thanks for using QandA platform
This typically indicates that the specified container or database doesn't exist or isn't accessible at the time of the request not that the stored procedure itself is missing. Even if the stored procedure doesn't already exist (which should normally result in a conflict error if it did), Cosmos DB will return a "NotFound" error if the parent container path is incorrect or not found.
verify that your SDK client is correctly configured with the right endpoint and keys. This issue can also happen if the container creation hasn’t completed yet in scripts or CI/CD flows. You can refer to the official docs on stored procedures and the troubleshooting guide for NotFound errors
If this helps kindly accept the answer thanks much.
