Mass animation transfer error?

I’m trying to transfer animations using the third party tool

but I keep getting this error. Has anyone else done this and if so, how do I fix this?

I’m not sure which tool you are using, but Bad Request usually means there is an issue with your payload, possibly due to a syntax error in any JSON or data you are sending.

I’m using this documentation: Transfer animations | Documentation - Roblox Creator Hub

It states that when you enter the page. It could be an error right now, or something is outdated. Either way Roblox could try looking into it but there might not be much success unless they do make the programs to transfer the animations.
