hi, i am currently testing kmm and i am building a small app with a simple api request generated with openapi generator. the get request was pretty straight forward now i am trying to implement a post request and i always get the error "java.lang.IllegalStateException: Fail to prepare request body for sending. " despite the correct declaration in the openapi file.

does anybody know if i need to change the openapi file in order to work properly with ktor or if there is a special setting i need for the generation? Openapi file is in the thread

openapi: 3.0.2
info:

  /login:
    post:

      requestBody:
        description: User credentials for login
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/UserCredentials'
      responses:
