[BUG] Error: Cannot find module 'iltorb'

[mtford90]

Environment

• chrome-aws-lambda Version: 1.19.0
• puppeteer / puppeteer-core Version: 1.19.0
• OS: Amazon Linux
• Node.js Version: 10.15
• Lambda / GCF Runtime: nodejs10.x

Expected Behavior

iltorb should not be missing since it seems to be bundled with the package.

Current Behavior

Error during lambda invocation:

Possible Solution

I noticed this line in the codebase:

 if (iltorb == null) {
    iltorb = require(process.env.AWS_EXECUTION_ENV !== 'AWS_Lambda_nodejs8.10' ? 'iltorb' : `${__dirname}/iltorb`);
  }

Given that i'm running nodejs10.15 I would assume this would have resolved to ${__dirname}/iltorb rather "iltorb" as it seems to have done from the error message.

Edit: read this wrong - it requires iltorb if NOT on 8.10. So am I supposed to be bundling and installing iltorb myself, then?

[mtford90]

I patched in iltorb using a layer and now i'm facing the following error:

2019-08-09T17:39:54.620Z	a93274ca-ddc6-54da-b100-210d6fe652f5	ERROR	Error getting browser instance Error: Failed to launch chrome!
/tmp/chromium: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

This seems similar to #37 and so I guess I'll follow that thread for this new problem.

Do let me know if there's an easier way to fix this iltorb issue or if perhaps I missed something when setting this up.

@mtford90 The issue is not (only) iltorb: that would be easy to fix.

The problem is actually the incompatibility with nodejs10.x, as stated in the README:

Due to unmet dependencies, the nodejs10.x AWS Lambda runtime is currently not supported.

You're right that this is related to #37, and I've actually uploaded those dependencies that you need here, but unfortunately it doesn't end there - you'd also need to bundle Fontconfig and at least one font.

Given that this setup is much more complex on 10.x it's probably best to just stick with 8.10 for now.

Closing this as a duplicate of #37.

Looks like the new nodejs runtimes are supported now.
This package works with the nodejs8.10, nodejs10.x and nodejs12.x AWS Lambda runtimes out of the box

I was able to get past the error with npm i iltorb

next error was Failed to launch Chrome! which I was able to fix (locally) using

const browser = await chromium.puppeteer.launch({
     executablePath: undefined
})

[simsketch]

For code that works locally and in production, you can try this

            const browser = await chromium.puppeteer.launch({
                executablePath: process.env.NODE_ENV !== 'production'
                ? undefined
                : await chromium.executablePath,
            })
