Issue with HTTP Module Adding Extra Characters to JSON Payload

Hello I Have a problem with the HTTP module Screenshots : I send a correct JSON to a webhook in make.com but when i send it the module add ":" at the end of the JSON so it can't be read in make. I tested the same operation in Postam and it work so I think the bug is from Clay.
