Hey there, @sgffgs! Thanks for reaching out in community! Sorry to hear you’re running into this - we definitely want to help. 

Hmm, are we able to double check the app connection here? There’s also a few other steps that may be worth giving a shot here.

To clarify are you seeing this error on a Create Page Post Facebook action step? Full transparency, there is a known bug associated with this error on that action but wanted to double check first before going down that route.

Thanks so much and looking forward to hearing back.
