AuthenticatorConfigModel always null

In my Authenticator spi implementation I get always AuthenticatorConfigModel null but I set isConfigurable to true in my AuthenticatorFactory.
Any help?
sorry for my poor english

Why do you create 2 threads on the same subject?
Just have some patience please and don’t flood this channel with duplicate questions.

I delete the other post sorry

Maybe you could put an example of your SPI on github or something because otherwise it’s just a guessing game on what may be wrong with it.
