Hi!

When I try to add section in the red rectangle I get the following message:

[400]

400 Bad Request

Bad Request

The browser (or proxy) sent a request that this server could not understand.

Without that section the video is generated really well? What I miss? I just want to change avatar from time to time. I follow the rules from here: https://docs.heygen.com/docs/replace-avatar-in-template

Please help me to sort that out.
