AWS Lambda - canvas.node: invalid ELF header

[AleksandarGT]

Hello, I have been trying to use ChartJsNodeCanvas with AWS Lambda + AWS Amplify, but I keep having problems with node-canvas with the error 'var/task/node_modules/canvas/build/Release/canvas.node: invalid ELF header'.

So far what I have tried is to use an AWS Lambda Layer for node-canvas: Lambda layer

Now when I import canvas it doesn't throw error and successfully console logs it

const canvas = require('canvas')
console.log(canvas)

However the moment I import chartjs-node-canvas it throws invalid ELF header.

{
    "errorType": "Error",
    "errorMessage": "/var/task/node_modules/canvas/build/Release/canvas.node: invalid ELF header",
    "code": "ERR_DLOPEN_FAILED",
    "stack": [
        "Error: /var/task/node_modules/canvas/build/Release/canvas.node: invalid ELF header",
        "    at Object.Module._extensions..node (node:internal/modules/cjs/loader:1282:18)",
        "    at Module.load (node:internal/modules/cjs/loader:1076:32)",
        "    at Function.Module._load (node:internal/modules/cjs/loader:911:12)",
        "    at Module.require (node:internal/modules/cjs/loader:1100:19)",
        "    at require (node:internal/modules/cjs/helpers:108:18)",
        "    at Object.<anonymous> (/var/task/node_modules/canvas/lib/bindings.js:3:18)",
        "    at Module._compile (node:internal/modules/cjs/loader:1198:14)",
        "    at Object.Module._extensions..js (node:internal/modules/cjs/loader:1252:10)",
        "    at Module.load (node:internal/modules/cjs/loader:1076:32)",
        "    at Function.Module._load (node:internal/modules/cjs/loader:911:12)"
    ]
}

I am confused, because the lambda layer provides node canvas version @2.11.2 which should be compatible with chartjs node canvas.

    "chart.js": "^3.9.1",
    "chartjs-node-canvas": "^4.1.6"

I can provide more information if this wasn't enough.

Any solution?

Remove chart.js as a dependancy in package.json and rely entirely on the lambda layer provided. https://github.com/charoitel/lambda-layer-canvas-nodejs/issues/19
