This error is with Expo React Native.

Everything was working fine until I ran the command expo build:android

Answer 1

In my case I just closed and re-open the terminal and ran below command:

expo build:android -t apk

Answer 2

Do nothing, just try again. It is not your problem.

Answer 3

I ran into a very similar error after updating my global Expo npm package. For some reason, an app that would always build crashed during building with that error.

As I hadn't done any changes to the actual app, I deleted the app/project from expo.io, and rebuilt it with the expo build command. This made the build succeed.

I'm just leaving this here as an answer, in case someone runs into the same error after updating Expo.

Answer 4

First time I had this problem, reason was I've used an invalid slug name in app.json, there must be a dash between the words as below:

  "expo": {   
    "slug": "My-App",

After a while I had the same problem,

1. I've realized that my expo-cli version wasn't latest one, I've updated it
2. Just closed and re-opened the VS Code and terminal as Zain said above in this page
