SM16 Mailing List Unsubscribe "Object Reference Not Set to an Instance of an Object" Error
Problem reported by Shaun Peet - 11/14/2018 at 8:54 AM
We've helped a customer get their mailing list updated to include the unsubscribe link in the footer, which links here:

But when clicking the button the "object reference not set to an instance of an object" message appears.

Using Postman to do a POST to the endpoint:

Returns the same error message.  But our error logs don't show anything so I don't know where to go from here.

Other mailing lists on our server have unsubscribe links that work just fine - it's just this one.  Thanks,

After applying the update from last night the issue still persists, except that now instead of an "object reference not set to an instance of an object" warning the message is "list not found".  But the list itself is generating the unsubscribe link so I'm not sure how that is possible.

We are going to delete that mailing list that the customer has created and then create a new one for them with the same settings / subscribers to see if that makes any difference.

This should be fixed in the latest release.
