Research direction

Start with the asynchronous listener callback and the native binding referenced in the stack trace, particularly napi_open_escapable_handle_scope. Reproduce the intermittent failure with the shown listener usage and trace the callback into pulsar.node. Done means identifying the locking issue and adding a verified fix or regression coverage.

Description

Hello, I am intermittently encountering an issue that appears to originate from the listener callback.

FATAL ERROR: HandleScope::HandleScope Entering the V8 API without proper locking in place

I defined the listener callback as follows to handle messages asynchronously:

await getPulsarConsumer({
    listener: async (message, messageConsumer): Promise<void> => {
      // do something
    },
  }

Can I know why this error occurred?
