how do I set cors headers with node js in my cloud functions
I am trying to add custom cors headers in my cloud function because I'm not able to access it with other domains. But im not able to add them with
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'GET, POST');
res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Authorization');
TL;DR
To set CORS headers in your Node.js cloud functions, add the headers using res.set() in your function code. Make sure the headers are set before sending the response.
Example:
```javascript
res.set({
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'GET, POST',
'Access-Control-Allow-Headers': 'Content-Type, Authorization'
});
```
Ensure the headers are set correctly and the response is sent after setting them. This should allow access from other domains. 
you would pass it as part of send or json. See https://github.com/open-runtimes/open-runtimes/blob/a3f20033b642d75096bc9754301e6d1525cebd1e/runtimes/node-18.0/src/server.js#L71-L90
