Brim CI failure: "TypeError: Cannot read property 'name' of undefined"

https:/brimsec/brim/actions/runs/677403237 was a run of the Brim CI that was triggered by the advance of the zq pointer. The run was at Brim commit 31bbcd0 attempting to run with zq commit brimdata/super@50bd002 (associated with brimdata/super#2386). The failure was in the "histogram deep inspection" test in itest/tests/ingest.test.ts and the failure was attached in this screenshot:

I've since performed a local run of the Brim CI using that combination of commits and was not able to reproduce the failure. A subsequent zq commit triggered a re-run of the CI and it passed, so the zq pointer has since been successfully advanced. This seems to indicate that the problem might be intermittent.

I was able to reproduce this by navigating to a workspace that did not exist. In the PR that fixes this, I'll add a global function called navTo(url). I'll add an integration test that does this too.
