Your ROOT_URL in app.ini is https://source.parasitstudio.de:63000/ but you are visiting https://source.parasitstudio.de/wirtz/MicroDexed/src/commit/acd4ec6bfc2c4f77b2a847825e4872005d91fbfb/third-party/ArduinoJson/extras/tests/JsonObject/size.cpp You should set ROOT_URL correctly, otherwise the web may not work correctly.
