I have created a federated identities which contains:

1. **Identity pool ID** us-west-2:XXXX-XXXXXXX-XXXX-XXXX-XXXX
2. **User Pool ID** us-west-2\_XXXXXXXXX
3. **App client ID** XXXXXX

When I try with **Identity pool ID** to connect to:
<https://cognito-idp.us-west-2.amazonaws.com/us-west-2:XXXX-XXXXXXX-XXXX-XXXX-XXXX/.well-known/jwks.json>

I get:

```
{"message":"1 validation error detected: Value 'us-west-2:XXXX-XXXXXXX-XXXX-XXXX-XXXX' at 'userPoolId' failed to satisfy constraint: Member must satisfy regular expression pattern: [\\w-]+_[0-9a-zA-Z]+"}

```

If I try with **User Pool ID** us-west-2\_XXXXXXXXX
<https://cognito-idp.us-west-2.amazonaws.com/us-west-2_xxxxxxxxxxxxxxx/.well-known/jwks.json>

```
{"message":"User pool us-west-2_ does not exist."}

```

How can I fix this?
