(node:528088) ExperimentalWarning: VM Modules is an experimental feature and might change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
node:internal/vm/module:306
if (module[kWrap] === undefined) {
^
TypeError: Cannot read properties of undefined (reading 'Symbol(kWrap)')
at ModuleWrap.<anonymous> (node:internal/vm/module:306:19)
at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

Repro case:

constvm=require('node:vm');asyncfunctionmain(){constmyObj={myProp: ''};constcontext=vm.createContext(myObj);constmodule=newvm.SourceTextModule('import * as bug from "bug";',{identifier: 'bug', context });awaitmodule.link(function(a,b,c){return});}main();

Should we add a test?

Also, cc @nodejs/vm.

[MikeRalphson]

@RaisinTen should that be a simple test of the exception type?

[RaisinTen]

I think so, yes.

[MikeRalphson]

Have found the relevant test file and am working up the new test function.

[MikeRalphson]

Is there a way to run just one of, or a subset of, the tests?

[RaisinTen]

Yea, you can run ./node test/parallel/test-rest-of-the-file-name.js to run an individual test

[MikeRalphson]

Thanks @RaisinTen!

You can also use tools/test.py test/parallel/test-rest-of-the-file-name.js or e.g. tools/test.py test/parallel/test-repl-* if you wanted to run all the REPL tests.

[fhinkel]

@MikeRalphson are you still working on the regression test or can somebody else pick this up?
