Expected Behavior

Obfuscating a dynamic import() call with a second options argument (such as { with: { type: "json" } }) should preserve the second argument in the generated output:

import('./data.json', {
    'with': {
        'type': 'json'
    }
});

Current Behavior

Obfuscating a dynamic import() that passes a second options argument parses without error since #1276 was resolved, but drops the second argument from the generated output:

import('./data.json');

This causes JSON or CSS module imports to fail at runtime with ERR_IMPORT_ATTRIBUTE_MISSING.

Steps to Reproduce

1. Pass import("./data.json", { with: { type: "json" } }); to JavaScriptObfuscator.obfuscate.
2. Inspect the output returned by .getObfuscatedCode().
3. Observe that the second options argument { with: { type: "json" } } is missing from the generated import() expression.

JavaScript Obfuscator Edition

• JavaScript Obfuscator Open Source

Your Environment

• Obfuscator version used: 5.10.0
• Node version used: v24.14.1

Stack trace

N/A (no exception during obfuscation; at runtime in Node.js, importing a JSON module without attributes throws TypeError [ERR_IMPORT_ATTRIBUTE_MISSING]: Module "./data.json" needs an import attribute of "type: json").

Minimal working example that will help to reproduce issue

const JavaScriptObfuscator = require("javascript-obfuscator");

const code = `import("./data.json", { with: { type: "json" } });`;

console.log(
  JavaScriptObfuscator.obfuscate(code, {
    stringArray: false,
    compact: false,
  }).getObfuscatedCode()
);
