I've reproduced the issue here: https://github.com/Garethp/localstack-testing/tree/base-path-mapping-deletion. When I clone down the branch base-path-mapping-deletion, run yarn install, and then ./start.sh I see the message
Failed to delete resource with id RestApiCustomDomainMapapigatewayRestApi11F5025C245D95DA of type AWS::ApiGateway::BasePathMapping
