When running an Expo app, you may encounter the error message 'Cannot read property 'getConstants' of null, js engine: hermes'.

I don't know the reason and I don't know where to fix it.

I upgraded the SDK from 46 to 48 (used the command 'expo upgrade')
deleted the node_modules folder, and reinstalled using yarn Install.
However, when I tried to run it, an error appeared.

I used the command 'npx expo start' to run it.

I want it to be tested live on the Expo Go app.

please help me.

I know that this is not the final solution, but try to run without development build, instead try to use expo go. That works for me.
