I had a working setup of communication between Electron and a regular Node application via Node-IPC in Electron 4.1.5. After no changes except upgrading to Electron 6, I can only send IPC communications out from Electron. Electron cannot receive responses via Node-IPC. Receiving messages fails silently.
I scoured the documents, release notes, blog posts, issues threads, Stack, and the Electron Slack channel for any leads, but I've found absolutely nothing.
I'm making my IPC connection from the main process, not a renderer, so the chromium-sandbox theoretically shouldn't be a factor, if it's even enabled by default which I'm not sure that it is.
My question is, what changes in Electron 6 have potential to affect a previously working inter-process communication setup?
