In the contributor PR workflow, we see failures with some component tests because we're trying to access a property on an undefined object in the runner code. For example.

This PR adds optional chaining and null checks so that we don't throw an error here. Still don't know why this is different from running the tests with an internal author but it is.

We can probably remove even more of these since the error is fixed now - most of them were excluded because of this issue I believe. I want to do that in a different PR though, since we can't test the contributor workflow until it's merged into develop

Do we know if there is a way to get snyk to run on contributor PRs? Looks like @young-robot doesn't have access to run those from his github context?

out of curiousity, why did you need to touch this code?

this code was throwing errors in the app component tests job for some reason - see the link to the failure in the PR description. This is what fixes those tests in the contributor workflow

Weird. Are those component tests retrying? I'm just trying to figure out why that would happen because there should be a previous attempt here if the currentRetry is 1 or more. I'm more so concerned there is some time of regression here, but I have no idea why this would be specifically on contributor PRs. any idea? I'm also OK with patching this after we get builds working it isn't a must to figure out right now imo

I'm going to approve this, but I really think we should figure out what is going on in the runner for previous attempts and if it is a signal for bugs. Tracking this down would be difficult I suspect and don't think it should block this PR, but it is something we should investigate
