Description John Matthews 2023-01-23 16:07:37 UTC

Description of problem:

A user is seeing consistent behavior in their environment that each time they click to view the migrations from a MigPlan the UI page fails to render with a javascript exception of:

"Cannot read properties of undefined ( reading 'name' )"

Version-Release number of selected component (if applicable):

Seen on MTC 1.7.6


How reproducible:
Consistent on the user's cluster for each MigPlan.
Seen with 2 different browsers and an incognito window so we don't believe it's related to browser cache.

Observing the behavior via a remote screen share I did see a brief render of the UI page for 'migrations' and ~1 sec after seeing it render, I saw the page go blank from the javascript exception.

Unable to reproduce on our engineering clusters.

Steps to Reproduce:
1. Unknown

Engineering was unable to reproduce the bug but a review of the impacted code showed a problem we believe is causing the issue.
@Ian Bolton posted a PR to address: https://github.com/migtools/mig-ui/pull/1484

@QE I do _not_ have clear reproducible steps as we couldn't reproduce in our environment yet this was consistent in user's environment.

The user saw this consistently each time they'd click the link to view the migrations of a given plan.  This was seen on successfully completed Migrations.

Verified using MTC 1.7.8 prestage
