Fix wrong Content-Type header
APIs expect specific Content-Type (e.g. application/json). Wrong or missing header causes 415 or parse errors.
Common causes
- Sending JSON without Content-Type: application/json.
- Charset missing for non-UTF-8.
- Boundary missing for multipart.
How to fix
- Set Content-Type: application/json for JSON.
- Include charset when needed.
- Use Content-Type Parser to inspect.
