I had a workflow working fine for months. All of the sudden the flow keeps failing with error message Bad gateway. I tried numbers of approaches to resolve the issue: copied the workflow, recreated it. run the connection in different account, clear cache, new browser session. non seems to work. However, When I tried to plug in different site and library to the flow, the flow runs successfully. I really need help on this. Thank you.
The action fails with error is the get change for an item or a file (properties only).
