Synchronous XMLHttpRequest on the main thread is deprecated

[csentanceParticipant]

Hi guys,

I’m a real newbie but am learning. I’ve developed a simple tewst app which runs fine locally. I’ve deployed it to my web server and am seeing a warning: –

jqxdata.js:7 Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/. (The line of code is M.open(e.type, e.url, e.async)

And then an Internal server error 500 error in jqxdata, line M.send((e.hasContent && e.data) || null ); This is when my webservice URL is called.

Any help to diagnose the issue would be appreciated.

Thanks,
Chris
