Accessing Cognito Custom Attributes in a post-confirmation lambda function
I have a post-confirmation lambda function that writes user attribute information to a dynamoDB table. I've managed to get access to standard user attributes fields in the "event" parameter by doing stuff like
event.request.userAttributes.sub
but trying to run
event.request.userAttributes.role //where role is the name of my custom attribute
doesn't seem to work. Anyone know what the proper syntax for this is? And do I need to set any special read permissions for custom attributes? I created this custom attribute a long time after I originally made this user pool, if that changes things.

All custom attributes are prefixed with the custom: prefix (Documentation - Custom Attributes).
Therefore (I'll assume you're using JavaScript here- if not feel free to specify and I can change this example), you'd need to use:
event.request.userAttributes['custom:role']
You don't need to set any special read permissions- all the user attributes are returned in the PostConfirmation lambda.
