Error 500 when checking server URL

[casimir]

I’m on iOS and I’m getting the same error. Self-hosted, running Wallabag 2.6.2, https, NGINX server…

Web server giving a 500:

[07/Aug/2023:00:17:07 +0100] "GET /api/info.json HTTP/1.1" 500 68 "-" "Dart/3.0 (dart:io)"

Works fine from the browser on my phone.

Server's log:
