"Cannot find module '/var/task/thread.js'" in AWS Lambda

[tonisives]

Weird error happens in AWS Lambda environment only. It works locally.

I am using solidity-code-metrics in my project. If I include the const surya = require('surya');, then the lambda fails with this uncaught exception. It isn’t even caught my try {} catch block. So this isn’t a normal crash

If I remove the surya import, then the the lambda manages to finish.

Error with surya import enabled

Please note I have made some patches to get SCM working in Lambda. But this one seems to be a new one from changes from max 1 year ago.

I tried surya 0.4.6 and also an update to 0.4.11
