Unhandled Communication Fault occurred

Question

Hi,

Am trying to update the Project team, calling the QueueUpdateProjectTeam on adding the team row and passing the team data set to the QueueUpdateProjectTeam method, but getting an error 'Unhandled Communication Fault occurred'. I looked into event viewer there the error is 'Connectivity exception [NullReferenceException] Object reference not set to an instance of an object'.

I checked further into the ULS logs, there I found the following error every time this method is called:

'GetUserInfoFromMembershipProvider: Request is in a web context and we can't find the user so we are failing. WebApp: 'e86387fe-e618-488a-946d-1394a508f375', LoginName: 'i:0#.w|nt authority\iusr', bIsRole: 'False'.' with category Authentication Authorization.

This error indicates something is fishy w.r.t logged in user calling the service, but my other calls to update project is working fine with the same user.

Does anyone have any idea on how to get rid of this error.

Many Thanks.

Cheers,

Amit

I had this issue when my cache accounts were disabled in AD. Try to login to web site with superuser account to check if this is your case.

If it is, you have to enable accounts in ad.

Perhaps you will need to configure them again in web application policy and properties:
