I have a single `apiId` with two versions:  
`https://api.getpostman.com/apis/{{apiId}}/versions`

```auto
{
    "versions": [
        {
            "id": "v2",
            "name": "Two",
            ...
            "lastRevision": 16598951405
        },
        {
            "id": "v1",
            "name": "One",
            ...
            "lastRevision": 16561247529
        }
    ]
}

```

In order to create a collection from schema, the `schemaId` along with `apiVersionId` are to be provided.  
`https://api.getpostman.com/apis/{{apiId}}/versions/{{apiVersionId}}/schemas/{{schemaId}}/collections?workspace={{workspaceId}}`

I’m unable to determine the `schemaId` for `v2`. Retrieving the single API only responds with `v1`:  
`https://api.getpostman.com/apis/{{apiId}}`

```auto
{
    "api": {
        "id": "api1",
        "name": "API",
        ...
        "versions": [
            {
                "api": "api1",
                "id": "v1",
                "name": "One",
                ...
                "schemas": [
                    {
                        "id": "schemaId",
                        "type": "openapi2",
                        "language": "json"
                    }
                ]
            }
        ]
    }
}

```

Retrieving the schema for `v2` using `schemaId` fails with:

```auto
{
    "error": {
        "name": "schemaApiVersionMismatchError",
        "message": "The Schema ID provided does not belong to the API Version ID provided."
    }
}

```

Both schemas against the API are synced via GitHub integration.

I’ve stopped using schema sync via GitHub integration and it’s responding with both schemas.

Hi @zhe.wang

I tried to retrieve Schema ID for different versions and that worked fine for me. One time where I faced the issue - when I used version name instead of version Id for the schema, could you check if the same helps you? Below is the collection that helped me to retrieve this:
