Your colleagues are importing the realm file through admin console, right? That won't work because you did full export (you exported all the realms to the file) and hence the file contains the array of realms, not single realm, which admin console expects.

To fix it, you can either:
1) Export just the single realm instead of all realms. You can do it by adding the additional property -Dkeycloak.migration.realmName (See docs for details). In this case file will contain just one realm and your colleagues can import it via admin console

2) Your colleagues will import file with all realms at startup with the system properties:
standalone.sh -Dkeycloak.migration.action=import -Dkeycloak.migration.provider=singleFile -Dkeycloak.migration.file=carewexmh-realm.json
but not through admin console.

Case (1) is when you want to export and import just one realm. Case (2) when you want to export and import all realms including master realm.

Hi,

I created a realm in keycloak 1.2.0-RC1, exported it with the following command

standalone.sh -Dkeycloak.migration.action=export -Dkeycloak.migration.provider=singleFile -Dkeycloak.migration.file=carewexmh-realm.json

Unfortunately my colleagues are unable to import the exported realm file, and when I intentionally delete the realm and try to import it myself, I get the same exception as they do. Any idea what's wrong?

Find the stacktrace below. If I need to include the jon file, do let https://github.com/aerogear/aerogear-unifiedpush-server-integration-tests/blob/rewrite/tools/test-extension/server/src/main/java/org/jboss/aerogear/unifiedpush/test/KeycloakConfigurator.java#L96-L121me know and i'll include it.
