Translator plugin: handshake Timeout #37

I’m trying to run examples from the this repository.
I fetched the repo, switched to the logseq-a-translator dir, ran npm instal, then npm run build.
It has successfully built the dist and I installed it in Logseq.

However, upon enabling it I receive a message:

ERROR: [Loader:#_ifb2iwsl4 - logseq-a-translator][8:21:38 PM] loadhandshake Timeout Error: handshake Timeout
    at file:///tmp/.mount_LogseqMcGrxd/resources/app/js/lsplugin.core.js:2:88419
    at g (file:///tmp/.mount_LogseqMcGrxd/resources/app/js/main.js:3608:419)

Ideas?

I also created a thread in the Discuss forum:
