error Cannot read properties of undefined (reading 'pid')
First I followed https://reactnative.dev/docs/hermes/ then https://reactnative.dev/docs/profile-hermes
Recording a Hermes sampling profile seems to succeed (hermes-profile-transformer is in my node-modules at version 0.0.6) Then the command to convert and transfer the Hermes tracing profile fails as follows:
$ npx react-native profile-hermes ./dev
