body type string is not recognized

See original GitHub issue

When expecting a body parameter of type string (not a json!) - an error is returned saying the body parameter is not a string even if it is. Bellow is a sample yaml code that shows it. The references are for the definitions of the id param and the returned values (not relevant here).

    - $ref: '#/components/parameters/idParam'
        - Users
      description: Set user role
          $ref: '#/components/responses/NoContentResponse'
          $ref: '#/components/responses/ErrorResponse'
              type: string
                - user
                - moderator
                - admin
        description: New role
        required: true

Thanks! That was the problem 😃 In the code I added: app.use(express.json()); app.use(express.text());

Not sure there is anything you can do in the validator in this case. Maybe extend the error message after saying it should be a string, add the type you got - in my case i believe it was undefined (it was not a json and there was no parser for text so req.body left undefined) maybe adding the typeof req.body to the error message info will help. But I’m not so sure about this.
