crash when using aws-lambda instrumentation

See original GitHub issue

I’ve been running into an exception where the JS auto-instrumentation attempts to load package.json from the base path of a lambda handler. Is there a way to customize the path from /var/task/src/handlers/my-function-name/package.json to a higher level /var/task/package.json or /opt/my-extension/package.json?

Copying the package.json into the expected locations causes the instrumentation to work as expected, it would just be painful for the project’s build process.

Setup:

AWS managed Lambda Layer for ADOT JavaScript SDK and ADOT Collector
OpenTelemetry JS v0.18.0
OpenTelemetry JS Contrib v0.20b0,
ADOT Collector for Lambda v0.9.1
Node 12 runtimes
Serverless framework builds and deploys

Exception:

That’s what I was thinking. If the supportedVersions.contains('*') we shouldn’t have any reason to even attempt to find the package.json
