403 HTTP Status code not returning correct error message

[lifeofpavs]

Current behaviour

Trying to send data to the Events API with an unauthorized token returns Failed to parse JSON as the error code as res.json() throws an error.

Desired behaviour

Using an unauthorized token to throw Unauthorized as the error message rather than Failed to parse JSON as it can be misleading

I feel like adding:

 if (res.status === 403) {
        throw new Error("Unauthorized");
      }

to the fetch function on client.ts would solve the issue
