POST in inbox gives Error 500

    Hi,

    I now (re-)installed the Activity-Pub Plugin. But it just randomly works. Most of the time the following request just produces error 500.)

    From the Log of the Mastodon Instance (the access log from the wordpress system shows the same).
    Mastodon::UnexpectedResponseError: https://le-chat-a-velo.at/wp-json/activitypub/1.0/users/0/inbox returned code 500

    Some requests eventually get through. But

    I tried disabling various plugins without success. The Error-Log of wordpress or PHP.

    Any hint what might be causing this – or at least how to debug what is going on?

    Greetings, ulrich.

    Hi,
    After a bit of playing around, we observed the following:
    Pixelfed <-> WordPress works reliable.
    Mastodon <-> WordPress does not work – gives the 500 on the POST reqest to the inbox.

    We cleared various caches on both sides, enabled and disabled caches etc. with no difference in the outcome. We also tried 2 different Mastodon Instances with the same result. (Mastodon versions 4.2.0 and 4.3.0 alpha).

    What I observed is, that sometimes the followers even end up in the database of wordpress. But for the failed requests the “activitypub_user_id” meta attribute to the follower is missing. However manually adding it does not change the behavior (it just shows up in the list in the admin-panel afterwards).

    key problem for me is how to find out what causes the 500 – since the log is empty.

    Cheers, ulrich

    hey @uk03 thanks for all the informations and your debugging work!

    Do you have a GitHub Account? I think this is more a development issue and not a classic support question, so I would love to track it here https://github.com/Automattic/wordpress-activitypub/issues

    Can you file an issue? Otherwise I would try to copy all your informations properly.
