That's a bit odd, it's this line https://github.com/flarum/core/blob/v1.0.4/src/Http/Middleware/AuthenticateWithSession.php#L41

$token->user should never be null because it's retrieved from access_tokens.user_id which is an enforced non-null foreign key to the users table.

Can you maybe verify your access_tokens table correctly has non-null values for the user_id column and that the foreign key constraint has not been deleted?

Confirmed.

I don't see any third-party middleware in the error trace so that's very curious.

Did you experience the error while visiting the site yourself? Is there a single occurrence or does it happen regularly?

clarkwinkelmann No. It only happened after I enabled Sasha's extension. Removing yes resolves the conflict
