Incompatible with NestJs v11.0.0

[BlueFits]

Description of the bug:

While trying to use the new gemini SDK in my nestJS server I get this error:

err:

require() of ES Module path-toproject\dist\gemini\gemini.service.js not supported.
index.js is treated as an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which declares all .js files in that package scope as ES modules.
Instead either rename index.js to end in .cjs, change the requiring code to use dynamic import() which is available in all CommonJS modules, or change "type": "module" to "type": "commonjs" in node_modules\.pnpm\@google+genai@1.0.0_@modelcontextprotocol+sdk@1.11.2\node_modules\@google\genai\package.json to treat all .js files as CommonJS (using .mjs for all ES modules instead).

I've tried updating my config and using dynamic imports, but it doesn't seem to work. Can this be addressed?

Actual vs expected behavior:

Server is unable to start

Any other information you'd like to share?

Note:
Server is unable to start to import the bundle properly, can be fixed by changing tsconfig props but that is incompatible with NestJS configurations

did you try ESM style when importing gemini SDK?

did you try ESM style when importing gemini SDK?

it's already using ESM, its written in typescript and then bundles it to commonjs which I assume is what causes the require to be used, but if esnext is used to bundle NestJS does not play well with it

Hi , any update about this , I get the same error using it with nestjs with the new geminis using this sample (doc's example)

import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({ apiKey: "YOUR_API_KEY" });

async function main() {
  const response = await ai.models.generateContent({
    model: "gemini-2.0-flash",
    contents: "Explain how AI works in a few words",
  });
  console.log(response.text);
}

No fix yet unfortunately :( I reverted back to the old sdk

Have you set "type":"module" in your package.json?

I also encountered the same mistake😣

@google/genai: "1.23.0"
@nestjs/core: 11.1.6

Im having the same issue. @jkrmarmol did you set type: module in your package.json? This introduces other issues
