Hi everyone, I'm trying to use the new feature that allows sending custom headers, but I can't seem to get it to work. Additionally, I couldn't find any documentation about this feature, so I'm not sure if I'm missing something or if there's a specific configuration required. I've attached a screenshot of the GUI where the error appears. Hopefully, it provides some clarity. If anyone has experience with this feature or knows where I can find some documentation, I'd really appreciate your help! Thanks in advance! https://cdn.discordapp.com/attachments/1211484481848873020/1315718692100771971/Screenshot_2024-12-09_at_10.28.27.png?ex=67586e05&is=67571c85&hm=5899644247513f22f67a62cf27b2f23c352cabc437e5cd8f829de0a6670ccf3f&
