What steps will reproduce the bug?

I'm using esbuild to generate a very small source map for the next code:

const { getSourceMapsEnabled } = require('internal/source_map/source_map_cache');
console.log(getSourceMapsEnabled());
throw new Error();

I'm calling an internal function I found to see if the source maps are enabled. Here's the code, esbuild spits out:

// test.js
var { getSourceMapsEnabled } = require("internal/source_map/source_map_cache");
console.log(getSourceMapsEnabled());
throw new Error();
//# sourceMappingURL=data:application/json;base64,ewogICJ2ZXJzaW9uIjogMywKICAic291cmNlcyI6IFsidGVzdC5qcyJdLAogICJzb3VyY2VzQ29udGVudCI6IFsiY29uc3QgeyBnZXRTb3VyY2VNYXBzRW5hYmxlZCB9ID0gcmVxdWlyZSgnaW50ZXJuYWwvc291cmNlX21hcC9zb3VyY2VfbWFwX2NhY2hlJyk7XG5jb25zb2xlLmxvZyhnZXRTb3VyY2VNYXBzRW5hYmxlZCgpKTtcbnRocm93IG5ldyBFcnJvcigpO1xuIl0sCiAgIm1hcHBpbmdzIjogIjtBQUFBLElBQU0sRUFBRSxxQkFBcUIsSUFBSSxRQUFRLHNDQUFzQztBQUMvRSxRQUFRLElBQUkscUJBQXFCLENBQUM7QUFDbEMsTUFBTSxJQUFJLE1BQU07IiwKICAibmFtZXMiOiBbXQp9Cg==

If you were to write this to a file, say otherFile.js and run it like so:

node --expose-internals --enable-source-maps otherFile.js  

You would see the source maps are being used correctly, replacing the name of the file with the name of the original file ("test.js").

true
/tmp/test.js:3
throw new Error();

However, if you were to pipe it through stdin, the source maps will not work and instead you'll just get [stdin].

cat otherFile.js | node --expose-internals --enable-source-maps

true
[stdin]:4
throw new Error();
^

How often does it reproduce? Is there a required condition?

No response

What is the expected behavior? Why is that the expected behavior?

It should probably build a stack trace with the source map information.

What do you see instead?

Source maps are not being used.
