Problem occurs when provisioning clients. Error: 409 Conflict while running a brick

Hi, I am using goodata, amazon RDS and Redshift.

I have added the user in Redshift and I am super admin in both redshift and gooddata.

Now when I try to run a brick it gives me this error:

```

Problem occurs when provisioning clients. Error: 409 Conflict

```

Next, I added a new user as I thought the user already existed with different credientials and identities but again the same error occured.

Can someone help me to troubleshoot it?

This is the script I am running :

```

{
  "segments_filter": ["PRODUCTION"],
  "redshift_client": {
    "connection": {
      "url": "${Production.url}",
      "authentication": {
        "basic": {
          "userName": "${Production.username}",
          "password": "${Production.password}"
        }
      },
      "database": "${Production.database}",
      "schema": "workspaces"
    }
  },
  "input_source": {
    "type": "redshift",
    "query": "SELECT * FROM workspaces WHERE active = true;"
  }
}

```

Thanks in advance!
