Wrong content-type on retry for POST

[rlsystems]

I'm having this issue in two separate projects, Vue and React:

React:
On a POST retry attempt, it will fail and get 415 unsupported media type because the header for content-type is being set to plaintext; it should be 'application/json'. However, a POST with form data like when I upload a file, works; the retry is set correctly to 'multipart/form-data'.

Vue:
Same issue with Vue, a 415 unsupported media error response, except with Vue the content-type header is being set to 'multipart/form-data' when it should be 'application/json'. Uploading a form data POST works ok here too.

Has anyone else had this issue?
