Hi averyone. Need help. I got the issue in Node-red
````auto
require() of ES modules is not supported.
require() of /home/ubuntu/scalar-crm-integration/externalModules/node_modules/node-fetch/src/index.js from /usr/lib/node_modules/node-red/node_modules/@node-red/registry/lib/externalModules.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /home/ubuntu/scalar-crm-integration/externalModules/node_modules/node-fetch/package.json.```

Code example:
```auto
const getResourse = async (url, headers, retries = 3) => {
const response = await fetch(url, headers);
if (response.status !== 200) {
if (retries > 0) {
return getResourse(url, headers, retries - 1);
} else {
return {'statusCode':response.status, 'message':response.statusText};
}
}
return await response.json();
}
```
On the local machine thise code works

To use ESM modules with Node-RED you'll need Node-RED 2.x.

Check to see if you have the same version of `node-fetch` installed in both places. Perhaps you have an older version locally that can be required, rather than imported.
The fact remains, Node-RED wasn't updated to use `import` for external modules until 2.x.

Thank you for your help. I will try to update Node-red application to 2.x version
