If a module throws undefined, and another module imports it, it should catch undefined, like that in browser.
Browser Test
Make 2 files "index.html" and "aaa.mjs".
index.html:
<!DOCTYPE html>
<html>
<head>
<script type="module">
"use strict";
import('./aaa.mjs')
.then(m => console.log("ok"))
.catch(e => console.log("bad", e));
</script>
<title>test</title>
</head>
<body>
</body>
</html>aaa.mjs:
"use strict";
throw undefined;It will output "bad undefined". You can also visit my temporary page for this test: https://zzz-shadow.github.io/
Node.js Test
Make 2 files "test.mjs" and "aaa.mjs".
test.mjs:
"use strict";
import('./aaa.mjs')
.then(m => console.log("ok"))
.catch(e => console.log("bad", e));aaa.mjs:
"use strict";
throw undefined;When running test.mjs, it will output:
bad TypeError: Cannot read property 'stack' of undefined
at ModuleJob.run (internal/loader/ModuleJob.js:108:9)
So, in Node, when a module throws undefined or null, the thing caught isn't the thing it throws.
Static imports are also affected.
