The server throws an error：

`webrtc::FieldTrialParser::ParseFieldTrial() | Failed to read empty key field with value: 'Enabled' in trial: "Enabled,100"`

No, the server does not throw any error, it’s just a log. We are aware of it.

Ok, so you don’t see the video of another user and automatically assume that such a log is the problem. No, sorry, you’d see the same error log even when things work fine.

This is the **Leeryver Symptom** (in Spanish _“Leer-y-ver”_, in English: _“Read-and-see”_):

_“I never check the logs when things go ok so, when things are not ok I check the logs for first time and assume that the first warning/error log is the cause of the problem.”_
