Failed Task

[Pabbly User 123456]

It shows Failed but in reality it successfully posted on my group.

Workflow: Fb Page to Fb Post

Would be a big problem since it will be hard to track which post really failed.

This type of thing is difficult to pin down. The request was sent and processed (so it successfully posted), but the issue is that the response gave a 500 (generic error message). Nothing really can be done in this situation as this was the response Facebook sent back to Pabbly.

This is the status code coming from the API which states that the application has processed your request but is unable to show the response.
Kindly make some more submissions and then monitor your workflow for some time.
