Comment 3 for bug 1772674

Although the patch https://review.opendev.org/c/openstack/charm-openstack-dashboard/+/836797 was submitted and merged during the zed cycle (22-, unfortunately, the associated charm-helpers change (https://github.com/juju/charm-helpers/pull/691) wasn't merged. Therefore, the patch to the openstack-dashboard charm was overwritten at the next charm-helpers sync. These were

b27c840 [2022-05-10] Merge "Validate X509 certificate inputs" [Gerrit Code Review]
...
036a392 [2022-08-30] Merge "Add Kinetic and Zed support" [Gerrit Code Review]

Therefore, the code in b27c840 patch is no longer present.

This means that the patch/fix is not present in the stable/zed, stable/2023.1 nor master branches of the code. I'll merge the the code, and raise the backports.
