Kokoro: Build and Device Tests failing due to ... Firebase Test Lab internal bug?!

[vorburger]

This build for #2487 has failed e.g. here.

I've no idea what this means, and what could be causing this.

This looks like it's not (just) a "flaky test" in android-fhir anymore (such as e.g. #2485 et al.), but some... Firebase Test Lab internal bug?!

@jingtang10 @santosh-pingle how do we proceed here?

It looks like this was some transient issue, it works now! Just for the record, here's an extract from the full log (linked above):
