How to parse it using groovy script?

I used as

def requestBody = mockRequest.getRequestContent()
log.info "Request body: " + requestBody

But it is returning null, as the body is coming as form-data. (Message I am getting: Wed Nov 09 23:43:06 IST 2022:INFO:Request body: null)

Is there any way to parse the above request, at least print the body?
