Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Credentials' header in the response is '' which must be 'true' when the request's credentials mode is 'include'. Origin '<http://localhost:4200>' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.n

05/19/2017, 10:20 PM@nilan Hi, no browser extensions. I havent changed my code at all but it is possible the ng2-file-upload library has been updated and it broke something, which is what im looking into now

05/19/2017, 10:21 PMI also was messing with a function on File is Created to validate file size/contentType, and I had some permission queries set up on on the File Object. I since turned all of those off though and tried it again but I still get the same error message

05/19/2017, 10:50 PMYoure right, ng2-file-upload was setting the withCredentials flag on the XMLHttpRequest to true by default. Manually, setting it to false fixed the issue.
