One of our Power Automate flows has been working for months and months on end with no issues has now started failing with:
Flow run failed. Action 'List_files_in_folder' failed: The API
'onedriveforbusiness' returned an invalid response for workflow
operation 'List_files_in_folder' of type 'OpenApiConnection'. Error
details: 'The API operation 'ListFolderV2' requires the property 'body'
to be of type 'Object' but is of type 'Array'.'
This started on Saturday, May 16th, 2026 and has been failing since then.
Any word on Microsoft patching this or are there any workarounds anyone knows of?
Stems from these PA actions for the OneDrive connector: Get file metadata using path -> List files in folder
Or it does in my particular flow anyways.
