[keycloak-user] Import/export realm : Getting Client secret not provided in request for imported realm

I have exported realm from one keycloak server and imported into another but I keep getting below error if authorization is enabled i.e. in case of confidential client. *failed to turn code into token* *status from server: 400* * {"error":"unauthorized_client","error_description":"Client secret not provided in request"}* *I made sure my keycloak.json contains the client secret same as that under Realm->Client->Credentials. My client app is same i.e. same client app with server-1 works fine but something has been missed in export step which causes client app with server-2 to be not able to work.* Is any additional step is required for exporting? I have tried exporting both from Admin console GUI as well as this doc (through standalone.sh) https://www.keycloak.org/docs/4.5/server_admin/index.html#_export_import
