I have a set of three pages that I developed in a development instance; HTML page, a JS code resource responsible for GET requests and a JS code resource responsible for POST requests.
In the development instance everything works perfect.
Moved it into clients instance: In Firefox, everything works.
In Chrome and Safari my GET requests all fail with 500 errors, but by error handling turns around and does a post to log the error successfully.
Both are on the same domain so not a CORS issue, I have the
Access control allow headers on the code resource.
I feel like the fact that it works in Firefox rules out syntax errors on the get page...
