#215 Object of class stdClass could not be converted to string

From nginx error log:

"PHP message: PHP Recoverable fatal error: Object of class stdClass could not be converted to string in /var/www/gnusocial/classes/Notice.php on line 1264" while reading response header from upstream, client: 87.104.234.5, server: gnusocial.net, request: "POST /inbox.json HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.3-fpm.sock:", host: "gnusocial.net"

Access log:

87.104.234.5 - - [15/Nov/2020:17:21:53 +0100] "POST /inbox.json HTTP/1.1" 500 5 "-" "http.rb/4.4.1 (Mastodon/3.2.1; +https://manowar.social/)"

Can't fix with just that :/ Can you provide the received activity?

Ok! A recent one:
