I believe you will need to fix the failing test by updating the Jest snapshot files to match.
Otherwise, the pull request reviewers cannot merge your pull request.

The error occured because UI was updated recently to support toast notifications. we are about to update the snapshot too.

Thank you for creating this test. I appreciate that you tested the case where the user clicks on the header. I didn't know you could simulate the click through a snapshot test!
