Hi, I can’t understand what this warning is telling me what to do as the url is formed correctly there is no ‘=’ symbol?

WARN : You might have an = symbol in url. You better place ‘url=’ before, example: ‘url=/your-url/foo?param=a’ or use ‘/your-url/foo params=param=a’ or escape it

For a routing issue, you would most definitely get a 40x. If it’s a whitelist/VPN issue you should be getting a 40x as well… I have no idea how the service is configured, but when using Postman, your request will be coming from a different origin–so, a potential whitelist issue. You should be able to do some basic debugging on the server-side to see if you’re even getting to the controller for your endpoint.
