Pull Request Overview

This PR fixes an issue where the az functionapp deployment source config-zip command was uploading blobs without content. The fix changes the blob upload mechanism to explicitly read the ZIP file content before uploading instead of passing the file path directly.

  • Replaced direct file path upload with explicit file content reading
  • Added proper file handling with binary mode reading and path resolution

Tip: Customize your code reviews with copilot-instructions.md. Create the file or learn how to get started.


blob_client = container_client.upload_blob(blob_name, src, validate_content=True, progress_hook=progress_callback)
blob_client = None
import os

The import os statement should be moved to the top of the file with other imports rather than being placed within the function. This follows Python best practices for import organization.

The variable blob_client = None initialization on line 1669 is unnecessary since blob_client is immediately assigned a value within the with statement context.
