Hi everyone,

I started having some errors recently on my production environment and can't figure out what is going on. This is happening in a few test classes I run and by looking at the debug logs, all the tests go through everything as expected and after they are done and call test.stopTest(), the test enters managed package and things go bad. This is actually happening when entering Zendesk package, but I'm not sure if this is related to this specific package (could be some error that was being forwarded and ends up on last package or something like that).

The first thing I got was this:

Error MessageSystem.QueryException: No such column 'BillingAddress' on entity 'Account'. If you are attempting to use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe call for the appropriate names.
Stack Trace(Zendesk)

I don't make such query, Zendesk was making it when entering managed packages and doing a query with all fields of Account object. I don't know why that fails too, since "BillingAddress" does exist on Account object. Anyway, I was able to reproduce this first error on my Sandbox and commented the single test that makes this happen.

However, there was another error happening in other test classes, a NullPointerException also after the test.stopTest() is called on my test classes, then it enters managed package. This one I couldn't reproduce in sandbox, it just happens on production. These are the last lines of the debug logs for running one of the failing test classes.

I already opened a ticket on Zendesk support, but haven't received an answer yet, and since this is blocking me from deploying things, I decided to try developer forums, maybe someone had the same or similar issue and can give me some hint.

Any ideas?

Regards.
