Verifying Appwrite into React Native projects

Hello devs, as I start to develop React native applications, I am recommended Appwrite to establish database. In the add platform section, I am asked to clone starter project and I did it. I also headed to .env to assign project id and name, then started the project. After many times clicking on send a ping, the verify section is still waiting for connection. How can I get over this?

Also the log returns status 50, which idk what it corresponds to

The variables might not have been declared well.
Check your env file name i think it needs to be changed 🤔
Or you can apply the variables directly in the index file

One more thing, this is actually optional. You pinging is only just to check you have setup your environment right. You can follow tutorials to develop app without needing this ping
