Cannot convert undefined or null to object

Describe the bug

I am using Keycloak 19.0.3. This bug occurs also in 19.0.2 but not in 19.0.1

I am following the steps provided here: https://www.keycloak.org/docs/19.0.1/server_admin/#_step-up-flow

1. Add the Condition - Level of Authentication

2. Press the gearbox icon. This is what happens:

Version

19.0.3

Expected behavior

I should be able to see this dialog (which I can see if I rollback to 19.0.1)

The dialog is initially empty (no alias field, no loa-condition-level field). If I rollback to 19.0.1, fill the dialog and the roll-forward to 19.0.3, I can open the dialog and see the correct value as above. But pressing the Clear button cause the problem again.

Actual behavior

Currently it is not possible to set up a Condition - Level of authentication. The error is the one below.

** Important ** Looking at the old issues, it looks like the same error was found in roles and other authentication blocks. I currently did not test them but it is definitely possible they are affected too.

How to Reproduce?

Follow the documentation steps in the link I provided above (official documentation).

Anything else?

Please provide the “database compatibility” among minor versions. I can’t find this information and I took the risk to roll-back and roll-forward the container images while sharing the same database. More info about this would be greatly appreciated.

@raffaeler 20.0.0 was released a couple of days ago.

@ssilvert yesterday I checked for a new container release but the latest tag was the 19.0.3. Where can I find the 20? Was it released or is it a beta?
