e.CanvasRenderingContext2dInit is not a function

[carlesandres]

I am getting this error after following the steps in this repo.

e.CanvasRenderingContext2dInit is not a function

The way I construct my lambda is by bundling with Parcel from the function's entry point, letting it figure out what to bundle, then zipping it and uploading.
My bundle is definitely including a copy of canvas from my local node_modules folder and is very likely the cause of this error.
That said, I am new to lambdas and I find it difficult to infer from the readme how people workaround the issue of excluding the local 'canvas' module from the zip they upload to AWS.
If I managed to finally exclude my local copy of canvas from the zip it, is there a change that const Canvas = require('canvas') won't pick the canvas module from the layer?

@carlesandres It may be loading canvas from your node_modules directory. Make sure you're not deploying canvas with your function, you don't need it since it's already in the layer. Maybe just put it as a devDependancy.

Thanks. I’m sure is that. I’ve taken a detour from my original approach for now by using OffscreenCanvas combined with service workers to generate hi-res images on the client, but I will go back to this soon. I’ll let you know how it goes.
