don't know how to turn this value into a node at valueToNode (node_modules/@babel/types/lib/converters/valueToNode.js:98:9)

[AllanOricil]

Description

I started to have this problem inside Github Actions

It started 18h ago +-, without any changes to the pipeline, dev dependencies, or even jest config files.
Another weird thing is that I can run all the tests on my machine with no problem. I even did a fresh install to simulate what happens in Github to ensure I was not using cached dependencies.

1. Deleted lockfile
2. Cleared the cache with yarn cache clean --all
3. Deleted /node_modules
4. installed dependencies with yarn install
5. ran yarn test:unit and everything worked as expected

So it does not seem to be a problem with the dev dependencies, but I can't determine it for sure. That is why Im here asking for help.

my system info => all tests are executed with no problem

darwin-x64 - m1
node-v14.18.2
yarn-v1.22.10
npm-v6.14.15
sfdx-cli/7.135.0 

github actions info (we are using a docker image based on node:latest)

node-v17.4.0
yarn-v.122.17
npm-v8.3.1
sfd-cli/7.135.0

OBS: None of the following files were changed and the tests started failing. They fail only inside github actions. Locally I can run them without a problem.

some of the Babel packages were patched from .16 to .17

The issue is comming from this package:

https://www.npmjs.com/package/@babel/types

Could it be the cause?

[AllanOricil]

I was able to reproduce the issue locally with node v14.18.2 or v.17.4.0 so I can say it is not a node version issue, nor a problem with github actions. Also, nor a problem with our repo, since these testss passed on our last merge to our main branch.

Im almost sure that this update on Babel broke everything.

[nolanlawson]

It looks like your stacktrace has a reference to istanbul as well. If you disable code coverage in your tests (nyc, istanbul, etc.), do the tests pass?

[AllanOricil]

@nolanlawson I need to upload coverage on codecov.io. so can't disable it.
To fix our issue we installed an old version of babel and it's dependencies after yarn install with
npm install -D @babel/core@7.16.12

Maybe you could force babel core to stay at this version until you make this package compatible with babel 7.17? At the moment I think it is using ^ in the package and this allowed it to be bumped to 7.17 which broke the test.

[nolanlawson]

Could you run yarn why @babel/core? (Or npm ls @babel/core?) I'm not sure which package is depending on @babel/core and causing this problem. (There could be multiple, but one in particular is bringing in that version.)

@lwc/compiler is using a ~ rather than a ^. And I don't see where sfdx-lwc-jest depends on @babel/core.

[AllanOricil]

[nolanlawson]

OK thanks. Yes, it looks like @lwc/jest-transformer depends on @babel/core ^7.16.7: https://github.com/salesforce/lwc-test/blob/531577b24362a857a83d9ed6b14cc2a430308dc5/packages/%40lwc/jest-transformer/package.json#L25

This probably needs some more testing, but it may be an issue with the repo for @lwc/jest-transformer: https://github.com/salesforce/lwc-test

[nolanlawson]

Hm, updating all the dependencies in lwc-test passes the tests: salesforce/lwc-test#146

There is probably some specific combination of dependency versions that's causing this issue.

[pmdartus]

I was able to reproduce the same issue in a fresh SFDX project: https://github.com/pmdartus/sfdx-jest-instanbul-bug.

---

Update: This is a known jest issue. This issue is caused by babel/babel#14209, breaking Istanbul source map serialization. The Instanbul and Babel teams are currently working on fixing this issue (istanbuljs/istanbuljs#576).

There is, unfortunately, nothing we can do at sfdx-lwc-jest level to fix this issue since it is caused by internal Jest dependencies. Until the Istanbul patch gets released, I would recommend sticking to @babel/core@7.16.X. You could leverage yarn selective resolution to freeze @babel/core version.
