    javascript - Failed to execute 'send' on 'XMLHttpRequest' (but not a cross origin issue) - Stack

    My draft website works in FireFox and IE and in Android Chrome but does not work in desktop Chrome. Desktop Chrome gives me this error

    "Uncaught DOMException: Failed to execute 'send' on 'XMLHttpRequest'".

    Website URL:

    URL loaded in XmlHttpRequest: .json

    Failing in Chrome version: 56.0.2924.87 (Win 7)

    This error is usually a cross origin scripting issue but I am trying to load a JSON file (synchronously) from the same domain, port etc...

    Is Chrome blocking my request because I am doing an old-fashioned and deprecated synchronous request?

    • 1 Works fine in 64bit chrome 56 windows 10 - but really, learn how to use asynchronous code now before it's not just deprecated :p – Jaromanda X Commented Feb 15, 2017 at 8:25

    Reset to default 5

    In my chrome your url is working fine and data is getting loaded.

    Warning Message is there in chrome

    "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/."

    I think its just a browser issue and nothing else.. Just update your chrome.

    Chrome 56.0

    avoid making synchronous requests. Instead of this.. xmlHttp.open("GET", "http://google.", false); use true in place of false.

    The issue was I was behind a zscaler network, so the location of the json resource did not match the one expected for the server. So the XmlHttpRequest failed. I did not want to enable CORS for my site, so I include a default set of data in the page for browsers unable to open the full data set via XmlHttpRequest.

    So it was a cross origin issue after all.
