Uploading from a passed file stream to Azure blob works locally, but not in Azure

Question

I have a Python/Flask API app I have deployed to an Azure App Service plan (Linux/Python 3.8). Everything works locally as it should, but when I deploy it to Azure it fails. Here's the relevant code:

blob_client = BlobClient.from_connection_string(
    conn_str=__ams_storage_connection_string, 
    container_name=input_asset_name, 
    blob_name=request.files["video"].filename
)
blob_client.upload_blob(request.files["video"].stream.read())

When I test this in Postman I pass the video file in the Body/form-data as a file. request.files["video"].filename has the correct filename (abc.mp4). It fails on the upload_blob and the exception I get when this runs in Azure is "Connection string missing required connection details"

I'm stumped.

Any help is appreciated and TIA.

Solved my own problem, and now I really do feel stupid.

It turned out to be a mistake on my part. My environment variable for the "__ams_storage_connection_string" was 1-character different in Azure than it is in my development environment. Fixed that and it finally works in both local and Azure. When I copied it from my dev environment to paste it into the Azure environment, I missed copying the very last character.
