Version

29.7.0

Steps to reproduce

use ESM module,
use the latest typescript version - 5.6.3,
set "resolveJsonModule": true in the tsconfig.json,
in an source file with the tested functionality put something like this:

import { name } from '../package.json' with { type: 'json' };

console.log(name);

start a test suit, which tests functionality in the file changed before

Expected behavior

tests from the test suit are started

Actual behavior

● Test suite failed to run

SyntaxError: The requested module '../package.json' does not provide an export named 'name'

  at Runtime.linkAndEvaluateModule (../../../../node_modules/jest-runtime/build/index.js:708:5)

Additional context

workaround: instead of the named import, import whole json object:

import pkgJson from '../package.json' with { type: 'json' };

console.log(pkgJson.name);
