Jibri - Record a room with one participant

I think I already know the answer but I will ask nonetheless.
We’re hosting our own instance of the jitsi stack, including jibri.

I was wondering if it’s possible to record a room with only one participant?

When I tried to start the recording with a single participant, it was unsuccessful. But it works normally with 2 or more participants. And I don’t know if this problem is because of our configuration or it is actually not supported.

works for me
