String 'null' in picture

Hello community,

I am new here so be patient :slight_smile:

I have a question about Jitsi: We are using Jitsi as a part of our self developed software. When we are establishing a video conference than we`re getting a ‘null’ string in front of the username image.

Our developers checked our sour code and have found nothing which caused this behaviour.

Can anybody explain me why?
