Error: Internal error: Expected value to be neither null nor undefined

Does this occur consistently? Yes
Repro steps:

1. I created some Azure Functions
2. I deployed to it a couple of times
3. I removed it and added another
4. Hitting refresh, instead of removing old Azure Functions and listing newly added one, produces the error:

Action: resolveResource
Error type: Error
Error Message: Internal error: Expected value to be neither null nor undefined

Even signing out of Azure account and signing in again doesn't work, old list of functions appears, refresh doesn't work.

Uninstalling extension and installing it again does not work (!!!).

Are you still experiencing this issue?

The deleted Function App may have still existed in some capacity in ARM and that's why it was displayed, but our extension wasn't able to fetch any of the Function App details.

I don't know if that was a coincidence because my steps just took some time, but after I downgraded the extension to something like 1.1 or 1.0, and upgraded it again to the latest version, the problem disappeared. This was on the same day as the report.

Ok. We need to make the error message better on our end.
