Submiting case on Microsoft Portal causes a Sequence contains no elements exception

(0) ShareShare
ReportReport
Posted on by regex91

Hello experts,

I created a customer self-service trial portal to test out Microsoft Portal technology,

and there is an error message when I try to submit a case on Portal to Dataverse.

I tried every possible solution, case creation just works fine in Dynamics 365, only broken on Portal.

Here is the error I got:

Server Error in '/' Application.

Sequence contains no elements

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Sequence contains no elements

I I enabled diagnostic logging, but when I reproduce this problem, the same exception appears in blob but nothing really useful.

Here I attach the relevant diagnostic message:

    RE: Submiting case on Microsoft Portal causes a Sequence contains no elements exception

    Hi,

    I had the same issue and in my case the user portal I used to perform case creation had a Parent Contact set with a Contact and not an Account.

    Seems stupid, but replacing the parent contact with an Account worked for me.

    Have a nice day.

    Eduard.
