Event Registration failed for some events only

Posted on by 115

Working with the last portal sample version (October 2020) and having customized the Angular Portal from version October 2020 also, we have problems with event registration attemps.

For some events, we can perform it without any problems.

However, there are some of them which causes error  Event registration failed

If we go to the traces of the plugin triggered (PortalCGIApiHandler), we barely can see different between both RegistrationResults, as you can see here:

On the left, the succesfully registration, on the right, the failured one.
Here you can see what we are sending to the service, being the same thing for both attemps:

Any clue of what is happening to us?
It cannot be due to Portal version or Portal Data, because it works for several events...

    Hi there Shravan.

    At the end we did not open any ticket.

    We restore both the Angular Application and the Portal Data (by using Configuration Migration tool), to the default OOB state.

    And the event registration for that event kept failing, so we assume that is something related to the event configuration itself.

    We are still in a developing phase and those were test events that we do not really need.

    So I guess that we will open that ticket if something similar occured to us in production

    Hey Manuel,

    Hopefully you were able to open a support ticket and get assistance from the team to get this sorted.

    Thanks

    Hi Manuel,

    The issue is similar to these two previous threads:

    https://community.dynamics.com/365/marketing/f/dynamics-365-for-marketing-forum/318085/event-portal-error-event-registration-failed-object-reference-not-set-to-an-instance-of-an-object/

    https://community.dynamics.com/365/marketing/f/dynamics-365-for-marketing-forum/363885/event-registration-failed

    I would suggest you open a support ticket to request investigation, the first user's issue was fixed by Support and confirmed as a bug of update.

    Regards,

    Clofly
