I am getting a strange error when trying to save this custom provider in KeyCloak.

Am I doing something wrong?
Thanks

Hello,
I'm currently trying to set up a new Keycloak instance (v19.0.2) and I'm getting the same error, only for a MySQL database.
Could it be some kind of version incompatibility?
Thanks.

Hello there, surprisingly this issue is related with the same problem others have reported before. as bizarre as it could sound, this issue is due to bug in the new keycloak theme. Please, check solution in #19 and try again. I have manage to configure an example using postgresSQL right now after changing to keycloak theme.
