Object reference not set to an instance of an object, when calling a custom action to send email notification

(0) ShareShare

Posted on by 62

Hello everyone, 

I am posting this question with a desperate need of help,

And to give you some context, we have a custom Action that sends email notifications and I have a plugin that calls that custom action and sends email notification.

It works when called from an administrator user and at top of Organization, but when I try to execute it from a different user from a child BU with different priviledges, I get the error. "Object reference not set to an instance of an object".

That 2nd user has still access to the parameters needed to send the notification, notification config ref, ent. logical and ID ( Regarding Case )

Any ideias what might be causing this, please?

Logs from plugin:

Custom Action:

Plugin Calling the action: 

      try
            {
                OrganizationRequest req = new OrganizationRequest("noesis_NotifyOnDemand");

                req["Target"] = notificationConfigRef;
                req["NotificationConfiguration"] = notificationConfigRef;
                req["EntityLogicalName"] = targetEntityReference.LogicalName;
                req["EntityId"] = targetEntityReference.Id.ToString();
                req["CreateAsDraft"] = createAsDraft;
                req["SplitToRecipients"] = splitToRecipients;

                TracingService.Trace($"Requesting Notification...\nParameters: {JsonConvert.SerializeObject(req.Parameters)}");

                OrganizationResponse response = Dynamics365Context.Execute(req);

                return response;
            }
            catch (Exception ex)
            {
                TracingService.Trace($"***Exception*** - Requesting Notification... Message: {ex.Message}, InnerException: {ex.InnerException}");
                throw new InvalidPluginExecutionException($"Exc. Message: {ex.Message}"); 
            }

    Thank you all for the suggestions. I have found out that this user was missing ReadAccess on Mailbox entity and therefore the plugin that sends notification returned "Object reference not set to an instance of an object." when trying to find the mailbox

    probably is the action itself that generate the exception, not the code you wrote to call the action.

    You should check inside the action code if there are some custom activities called and the code there

    hope it helps
