What is the meaning of 'No bundle URL present' in react-native?

Question

When I run a react-native project, I get a error no bundle URL present , but I don\'t know what mistakes I do, I was very confused.

Answer 1

This problem happens when you not allow unsecure connections via localhost, or maybe you tried to accept unsecure connections via http.

To fix this, add this on info.plist:

NSAppTransportSecurity
    
        NSAllowsArbitraryLoads
        
        NSAllowsArbitraryLoadsInWebContent
        
        NSAllowsLocalNetworking
