Unknown error while creating client using Keycloak REST API

Question

I'm trying to create a new client in my Springboot realm through the keycloak REST API using postman, but I'm getting an unknown error as the response.

The URL in post method is

localhost:8180/auth/admin/realms/springboot/clients

The header includes:

content-type - application/json
authorization - bearer <access token...>

The JSON body is

{    
  "id":"1",
  "clientId":"zzzzz",
  "name":"aaaaa",
  "description":"bbbbb",
  "redirectUris":[ "\\" ],
  "enabled":"true"
}

The response I'm getting is 403 : unknown error.

Answer 1

I obtained the same error because the client had not the necessary role.

• Go to Clients -> {your-client-name}
• Select the 'Service Account Roles' tab
• Add the necessary role. (In my case I needed the admin role)
