Generated API add text/plain to content-type header request

Describe the bug Generated API hook is adding text/plain to content-type header.

To Reproduce Generate API using the next definition:

post:
    tags:
        - security
        - legacy
    responses:
        '200':
            content:
                application/json:
                    schema:
                        $ref: '#/components/schemas/MenuItems'
            description: Success
    operationId: postGetMenu

Headers are set as follows:

  const myHook = usePostGetMenu({
    requestOptions: { headers: { 'Content-Type': 'application/json', Accept: 'application/json' } }
  })

And I make the request:

    myHook.mutate().then((value: MenuItems) => {
      console.log(value)
    })

Expected behavior I expect the request header to have content-type: application/json and not content-type: text/plain, application/json

Desktop (please complete the following information):

• OS: Windows 10 Enterprise
• Browser Chrome 80

Thanks in advance.

Noticed the same today. I have set 'Content-Type': 'application/json' on the <RestfulProvider /> and I am trying to override it on the component level on my useMutate() hook to multipart/form-data but encoutered the same issue. Sent content type was application/json, multipart/form-data 🤔

I have the same issue. It seems impossible to replace content-type, it’s just appending the types.
