I use API Gateway with a custom authorizer to authorize http requests based on a JWT Bearer token (header Authorization: Bearer <jwt>).
I activated the cache layer and I would like to invalidate the cache entry on specific resource when the resource has been modified.
With an IAM authorizer, I was able to test the cache invalidation mecanism described in this documentation https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-caching.html#override-api-gateway-stage-cache-for-method-cache . I used a lambda function to call the API Gateway assuming a role with the proper policy "execute-api:InvalidateCache".
The problem is that I want a use a custom authorizer instead of the IAM authorizer and it does not seem to be possible.
I tried to return the policy "execute-api:InvalidateCache" from my custom authorizer but the API Gateway does not authorize the cache invalidation.
Could you tell me if I am missing something or is it just not supported ?

Greetings Tim P,
We are attempting to address the same concern but are encountering a similar problem. Have there been any recent updates that provide support for cache invalidation in the context of AWS API Gateway when using Lambda authorizers?
