OIDC Authentication - attributes from Cognito

Using Authentication OpenId Connect and have troubles with Custom Attribute mapping

when Test OIDC > we can see that Unmapped Attributes list provides following attributes along with values

cognito:groups
cognito:roles

But having trouble to map these attributes. Question is how to map custom: attributes?

On the screenshot we can see available unmapped attributes with values.

When map to custom attributes,


Authentication doesn’t throw errors, neither picks up User Attributes Values

resolved by append [*]

If there are multiple values returned for a given path of the attribute, append [*] to the end of the path. *Example: groups [ *]
