I am having difficulty accessing azure blob storage using
Location='wasbs://CONTAINER@ACCOUNT.blob.core.windows.net/FILEPATH'
ds = fileDatastore(Location,'ReadFcn', @load, 'FileExtensions',Extension )
I keep getting the error:
Cannot find files or folders matching: 'wasbs://CONTAINER@ACCOUNT.blob.core.windows.net/FILEPATH'
this is confusing for me as the files and folders definitly exist. and this function has worked in the past. I have set the MW_WASB_SECRET_KEY and MW_WASB_SAS_TOKEN Keys environment variables correctly.

Hi @Sandy, these troubleshooting steps might help solve the issue:
  • Please make sure that the environment variables are set within the same MATLAB session where you are running your code.
  • Also, check that your SAS token or secret key has the right permissions for the files or folders you want to reach.
  • Ensure that your system has network access to Azure Blob Storage endpoints.
  • Try using the basic datastore function:
ds = datastore('wasbs://CONTAINER@ACCOUNT.blob.core.windows.net/FILEPATH');
If this command does not work, it likely means the problem is with the connection or the file path, rather than with fileDatastore.
Hope this helps!
