custom metadata triggers error

Hi, I’m using GStreamer to send an RTMP stream to Evostream, but unfortunately it’s not working. The server throws and error and refuses the connection:

From what I understand from the error, this is just some metadata. I understand EvoStream doesn’t have the feature of listening to metadata and manipulating it like other servers, but a critical error and connection rejection seems a bit extreme. Is there anything I need to configure to make this error go away? Thanks.
