@NaviTheCoderboi , @yigsvnsla replace type: 'multipart/form-data' with parse: 'multipart/form-data'. this enforces parsing the body as formdata

It's possibly due to multipart/form-data only allows transmission of files or strings. When you click "Send", the playlistId will get converted to String before sending to your server, which triggers validation error from Elysia. To solve the issue, set the type of this field to t.Numeric() : https://elysiajs.com/patterns/typebox.html#numeric
