ErrorParameterMismatch on Dynamics NAV Eventing.

Hey all,
This post is about events in Dynamics NAV 2016+. I was trying to subscribe to a standard event and faced an unexpected error which the publisher is running.

Error: ErrorParameterMismatch.

Then I realized that I have changed the Publisher event signature by amending the respected Subscriber event. Initially, it was ItemLedgEntry and ItemJournalLine, I changed it to ParamItemLedgEntry and ParamItemJournalLine.

Then I had to revert back in order to run the event trigger. Also, the event did not raise any error on runtime but lodged an error message on Event Subscriptions windows.

This is the warning message which I should have considered when setting up the event on function’s properties.

Voila, it worked after I reverted.
