Hi @Nanduri, Leela Krishna Reddy
Without a code snippet of how you're uploading the image, it's difficult to best assist you. However, here are a few things I would check when diagnosing such an error.
- Check to make sure your blob client along with other storage objects is being created without any issue.
- Verify the storage connection being used and configured is correct.
- Verify the container has been created first before adding blob. If it hasn't, make sure you include code to create the container on the fly.
- Add try/catch around the code interacting with storage and log the exception.
