Unable to run puppeteer or playwright examples

[agnieszka-ziaja]

After following the workaround listed here #1 (comment) I can finally get the function to invoke, but it fails to run puppeteer or playwright examples.

Puppeteer error:

Playwright error:

[info] Invoking /opt/index.handler (nodejs20.x)
[info] Error: An error occurred (InvalidParameterValueException) when calling the GetLayerVersion operation:
Invalid Layer name: arn:aws:lambda:us-west-2:760325925879:layer:AWS-CW-SyntheticsNodeJsPlaywright

I don't see anywhere to configure puppeteer to set the missing executablePath or channel values, and I think the missing playwright layer comes from your side as I don't recognise the AWS account ID 760325925879.

1. About puppeteer error, Are you using default script heartbeat-canary.js script or launching your own browser in script. How are you launching a new browser?
2. About playwright error, template included in this sample repo uses synthetics layer in us-west-2. You need to either set your default region as us-west-2 or pass region in launch arguments so that sam attempts to download layer from the correct region.

You can set default region by:

export AWS_DEFAULT_REGION=us-east-2

You can pass the region at invoke time as well:

sam local invoke NodeJSPlaywrightCanary -e ../event.json --region us-west-2
