I installed Project server 2013 on a SharePoint 2013 farm, everything goes well until I try to create a new view from "Project Web App Settings" page ==> the view doesn't get created (from the browser console I got

internal server error 500).

And from the windows events viewer I got the exception below :

Event code: 3003 Event message: A validation error has occurred. Event time: 24/11/2016 11:49:00 Event time (UTC): 24/11/2016 10:49:00 Event ID: f1579d278df048f480b1deee3faa1c49 Event sequence: 245 Event occurrence: 15 Event detail code: 0 Application information: Application domain: /LM/W3SVC/1513911398/ROOT-2-131244510754673622 Trust level: Full Application Virtual Path: / Application Path: C:\inetpub\wwwroot\wss\VirtualDirectories\443\ Machine name: VMXXXXSPO Process information: Process ID: 5128 Process name: w3wp.exe Account name: Domain\XXXX Exception information: Exception type: HttpRequestValidationException Exception message: A potentially dangerous Request.Form value was detected from the client (ctl00$ctl00$PlaceHolderMain$PWA_PlaceHolderMain$idGroupingSortingParams="0 at System.Web.HttpApplication.MaterializeHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

What could be the problem?

PS : I got the same error when trying to create calendar and when trying to add a user to a project server group.


This is what the PWA status looks like

This is what the PWA status looks like

I tried to restart the the timer Service without no result, the status is stuck on "Waiting for Resources"


Below the steps i do to reproduce the error :

Its like the save buton doesn't work and the view creation stack on the formulaire page.

PS : I have a frensh installation of project server

Thanks a lot.

  • what is the status of PWA instance ? is it provisioned ? Nov 24, 2016 at 13:55
  • After verification i found that the status of PWA is " Provisioning Failed - see the Application event Log. " !! which is weird because the status was "provisioned" after the installation and i didn't do any actions!

Make sure that The PWA instance has been provisioned properly at

Central administration > Application management > manage Service application > click on project server application server > check the status of your PWA Instance

  • @soukaouta , you said you tried to restart SharePoint timer service, but still, you got waiting for resources ? are you applied this for all app servers within your farm ? are you tried to provision pwa again after restart timer service ? Nov 24, 2016 at 17:09
  • The status is now Provisionned, i should have provisioned the pwa after restarting the timer sevice ==> Thanks for the information. However, the error when creating a new view still exist with the same log trace.

  • Still not working :( ps: the pwa portal is working fine and i can add projects and tasks ... normally, but the problem is when i try to create a new view from the "Project Web App Settings" page and also if i try to add a user to Project server administrators group ==> See picture below
