Jetpack conflict?

Hi, I’m getting PHP error messages from Jetpack that mention activity pub plugin, is there a conflict?

It does however seem to work, but I get these messages in my logs:

PHP ERROR: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function "_return_false" not found or invalid function name in /wordpress/wp-includes/class-wp-hook.php:308
