I have a web application on ASP that was built with Outsystems platform. On the page I have form and several AJAX requests. For some reasons on some computer (same application, same version of Chrome) AJAX request fails with 400 - bad request (Doesn't happen in IE or Firefox). I looked inside the request and on the verb part of the one who has error I have information from the viewstate of the previous AJAX request. (Also on the computer that have problems I tried to clean cookies, reinstall Chrome but it didn't helped.)

Please does anyone have an ideas with what it can be connected to?

Right request: enter image description here

Bad request: enter image description here

  • could you please provide both of those as text? and please also the code part where the post url is set? – Finn Sep 08 '16 at 11:29
  • What version of the OutSystems platform are you using? Are the misbehaving Chromes consistently misbehaving? If you try to use them in incognito mode will they still misbehave? – Miguel Ventura Sep 09 '16 at 10:48
  • I use 9.0, consistently, in incognito the same – Irisit Sep 09 '16 at 12:13
  • Can you check if the Chrome Developer Tools network pane shows information coherent with what Fiddler is showing? Is your application including any version of jQuery or some jQuery plugins? – Miguel Ventura Sep 09 '16 at 15:05
  • Did you check the log error in the service center? Its will help :) – Bruno Gomes Sep 11 '16 at 02:03
  • Did you perhaps find a solution on your own? – Hanno Apr 04 '17 at 19:54
  • My guess would be that the request is too long, IIS Express has a 64KB limit. That's checkable in Fiddler. – Jim W Apr 12 '18 at 18:20

I had similar issue with .net core and chrome with open DEVTOOLS. I used Fiddler to investigate, and the issue was because of some missing *.css.map files.

  • I've had the exact same issue and was using FF as a workaround. You can either add the .map files, or turn off _Enable CSS source maps_ / _Enable Javascript source maps_. – Mathemats Jan 23 '19 at 01:30
  • Let's note: In order to turn off css/js source maps, you need in DEVTOOLS settings (F1) uncheck checkboxes @Mathemats noted. – arturas Jan 23 '19 at 12:14
