When making a post request to https://g5xirepb1j.execute-api.eu-west-2.amazonaws.com/dev/post-test I get the error Failed to load https://g5xirepb1j.execute-api.eu-west-2.amazonaws.com/dev/post-test: Request header field Content-Type is not allowed by Access-Control-Allow-Headers in preflight response.
When researching this issue I found this reason -
Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources (e.g. fonts) on a web page to be requested from another domain outside the domain from which the first resource was served. This is set on the server-side and there is nothing you can do from the client-side to change that setting, that is up to the server/API. (MDN)
The first thing I tried was to change the header in the request, however this did not work.
I then found that you can bypass CORS from the client by adding the url of certain services to the request url (it is not recommended for production though!)
With some extra time I want to rigorously test the phone number and email validation functions with more edge cases.
