fix: add missing error status handler

[markwolff]

Which problem is this PR solving?

• Fixes gRPC tests fail on Node.js 14 #1004

Short description of the changes

• Adds a missing error status handler. Confused on why existing unit tests didn't pick this up until nodejs14. Will investigate separately...

[markwolff]

@dyladan I can add node14 to the circle tests on this PR, else I can confirm that they are passing locally w/ node14

[dyladan]

Think they are fundamentally separate issues as this is a true bugfix and the other is just administration. Would prefer they keep separate pr/issue/commits

[markwolff]

Makes sense. Passing locally for me on node14, other than a compile error here. I'm assuming its a bootstrapping issue on my end.
