batch-cluster.js hangs or errors out when used in a Docker container

[tvanc]

I'm experiencing two errors. I encountered the errors while using exiftools-vendored but I believe they come from this package. I created a minimal reproducible example to test and demonstrate.

The errors:

1. batch-cluster.js hangs if I call exiftool.read() for the first time in a Docker container's lifetime from within a Next.js request.
2. When I re-run the request batch-cluster.js fails immediately with the error: BatchCluster has ended, cannot enqueue …

The first error sounds just like #13, however as you can see my container definitely has the ps command.
