# Error: unable to verify the first certificate

###### When making request from a server (e.g. Node.js) to .local domain over https, the server may not have access to the LocalCan’s Root Certificates which is trusted on macOS, or doesn’t accept self-signed certificates.

For example Node.js (and so, other JS server frameworks) only take into account CAs from Mozilla CA store as supplied by the current Node.js version.

##### There are 2 solutions (choose one):

1. Add `RootCA.pem` to trusted CA list in your framework, so it can verify server certificate.
	
	In Node.js set `NODE_EXTRA_CA_CERTS` environment variable to point to `RootCA.pem`
	
	This could be done in couple ways, for example by editing `package.json` dev script, so every time you run `npm run dev` this variable will be set.

	```json:package.json
	...
	"scripts": {
		"dev": "NODE_EXTRA_CA_CERTS=/path/RootCa.pem node app.js"
	},
	...
	```
	
2. Disable certificate validity checks when making requests.
	
	In Node.js there is a flag you can set to false `rejectUnauthorized: false`
