I am trying to start a new react native expo app by executing
npx expo start but it throws following error

FetchError: request to https://api.expo.dev/v2/sdks/51.0.0/native-modules failed, reason: unable to get local issuer certificate

UPDATE

I am also getting same error when executing following command

npx expo install react-dom react-native-web @expo/metro-runtime

What could be the probably fix for this? Appreciate your advice.

I was facing the same problem, somehow it got something with proxy or network relative thing.
I using Linux Ubuntu and solve it by modify /etc/hosts .
I just define the requested Domain there like this.
```
127.0.0.1   localhost
127.0.1.1   ArifKurdi
104.18.4.104 api.expo.dev // The line I added in the file.
```
and Its work fine after that.

I’m on a company laptop, and I was able to resolve this by setting the NODE_EXTRA_CA_CERTS environment variable:

How can I set NODE_EXTRA_CA_CERTS on node

Some other solutions mentioned disabling TLS via NODE_TLS_REJECT_UNAUTHORIZED, but this doesn’t seem like a good idea for security reasons:
