A flow which has been working for several years suddenly failed with the following error:
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'.'
I have checked and reselected the folder path in the parameters to no avail. What else could be causing this issue?
