Uncaught server error: java.lang.RuntimeException: Unable to resolve auth flow binding override for: browser

I am trying to import my exported realm configuration in a new keycloak instance, but I am getting this error:

Uncaught server error: java.lang.RuntimeException: Unable to resolve auth flow binding override for: browser

What could cause this error? Why there is a binding error? First thing I can think of is that we have a custom flow for the browser and we a custom authenticator but the two setups are identical and have the same .jars files.

Is the import API reliable at all? I saw a lot of people complaining about it.

UPDATE:

Ok, looks like I have found the cause, sorry for the trouble

Hi! What was the cause of the issue? I am running into the same problem trying to import a realm.
