Description
Steps to reproduce
If necessary, delete the key mx_scalar_token_at_... from localstorage so that a new token is fetched.
- Press "Add widgets, bridges & bots"
- See "Cannot connect to integration manager"
Outcome
What did you expect?
Successful authentication with integration manager.
What happened instead?
Authentication fails due to bad request on the integration manager /api/register endpoint, as the content type header is this: Content-Type: text/plain;charset=UTF-8
This has started happening on v1.11.11-rc.1. On v1.11.10. the header is correctly set to application/json.
