Hi theminja ,
There are a few pieces here, more info is needed to see if this is a bug with any specific Swagger tool, or if this is more implementation specific. Couple of questions to help answer that.
1. What are you using in the backend? Was it generated by Swagger Codegen or other, or is it a framework?
2. How are you executing requests and where do you see the message "request/body/price must be integer".
Please be specific as possible, in order for us to see how we can help.
PS: The OpenAPI specification (fka Swagger) does support integers in multipart/form. So it sounds like an implementation issue or possibly a bug
