Module did not self register with Canvas Node in Serverless offline v12

[alexluongfm]

Bug Report

This is mainly to make this issue easy to google, and cross link with the canvas node not supporting worker_threads ticket. Similar to sharp module not registering issue.

Current Behavior
After running a handler, that invokes node-canvas once, the second and subsequent invocations gives a module did not self-register error. This gets fixed if I restart serverless offline

ANY /api/generate-canvas (λ: api)
✖ Unhandled exception in handler 'api'.
✖ Error: Module did not self-register: '/dev/serverless/node_modules/canvas/build/Release/canvas.node'.

Environment

• canvas version: [2.11.0]
• serverless version: [3.31.0
• serverless-offline version: [12.0.4]
• node.js version: [v18.16.0]
• OS: [Ubuntu 22.04]

Possible Solution

Worker threads not supported in canvas, need to switch to inProcess. This does mean hot reloading handlers doesn't work anymore, unfortunate.

Run serverless offline with the flag: --useInProcess.
Eg serverless offline start --useInProcess
