Getting ERR_PACKAGE_PATH_NOT_EXPORTED error in monorepo when updating to Node 16

[joshdura]

I am running a serverless application in a yarn workspaces monorepo. When trying to run the serverless offline command after updating to Node 16 (from Node 12), I get the following error:

The start script in my package.json file is as follows:

"start": "SLSDEBUG=* serverless offline",

Serverless versions here:

"serverless": "^3.2.1",
"serverless-domain-manager": "^5.1.0",
"serverless-offline": "9.2.6",
"serverless-offline-sqs": "^6.0.0",
"serverless-plugin-chrome": "^1.0.0-55.3",
"serverless-plugin-lambda-insights": "^1.0.10",
"serverless-plugin-split-stacks": "^1.11.0",
"serverless-prune-plugin": "^1.5.0",
"serverless-webpack": "^5.7.1",

Any idea what might be causing this (or any possible workarounds)? I have tried a complete reinstall via yarn as has been suggested in other articles I have read on this issue, but it doesn't work.

One other note, just went back down a version (to 8.x) and this issue doesn't happen.

Seeing the same issue on Node16. Was trying to switch to top level awaits but can't seem to go serverless-offline-9.x to start using this feature. Everything worked fine on serverless-offline-8.8, but that doesn't support top level await yet.

@joshdura @an1va

that's really weird. ./dist does not exist anymore in v9, which was the Babel compiler target in v8.

you might want to try some equivalent of npm update (yarn update?) or remove node_modules and yarn lock and force a fresh install.

if that doesn't help try to see if you have multiple versions of serverless-offline installed (since you mentioned monorepo).

if none of this helps I would like to ask you to create a really simple repro repository, but I don't think it will be needed.

Figured it out, it's actually an issue in the serverless-offline-sqs package. Linked here.
