Error: Unable to start Chrome

[ariel-frischer]

In AWS lambda I get this message. I can add the DEBUG variable soon to get more information.

{
  "errorType": "Error",
  "errorMessage": "Unable to start Chrome. If you have the DEBUG env variable set,there will be more in the logs.",
  "trace": [
    "Error: Unable to start Chrome. If you have the DEBUG env variable set,there will be more in the logs.",
    "    at /var/task/node_modules/@serverless-chrome/lambda/dist/bundle.cjs.js:376:13",
    "    at Generator.throw (<anonymous>)",
    "    at step (/var/task/node_modules/@serverless-chrome/lambda/dist/bundle.cjs.js:311:193)",
    "    at /var/task/node_modules/@serverless-chrome/lambda/dist/bundle.cjs.js:311:404",
    "    at processTicksAndRejections (internal/process/task_queues.js:97:5)"
  ]
}

+1 Same here.

Trying to install and deploy the exempel https://github.com/adieuadieu/serverless-chrome/tree/master/examples/serverless-framework/aws.
Only change made was a downgrade of serverless-plugin-chrome from "1.0.0-69" to "1.0.0-55.3" because the source was not found.

After deployment the pdf function throws Error 500, and here are the logs with DEBUG variable.

No apparent Fix.
Anyone fixed it?

[nealshail]

+1 here too, I'm getting a message

libnss3.so: cannot open shared object file

[lifesaverluke]

I've pre-compiled Lambda layers for various stable Chromium versions that work on AWS Lambda (they include the .so file mentioned above). They are available for download here.

[umihico]

Instead of fixing this, we can just use native chromium with certain conditions, JFYI.
