[Bug] Issue tracker not linked on all errors

Some errors have a “Create Maniphest Task” button while others show “Link Issue Tracker” button.

Refreshing the page doesn’t help i.e. it’s not a transient error. Refreshing shows the same button the page had before the refresh.

On pages that have a “Create Maniphest Task” button the integration works fine, so it’s not an issue with the integration either.

Why does this happen?
