How to fix TypeError: Cannot read property ‘packagerOpts’ of null, js engine: hermes
I noticed that my project had many npm security issues so, I decided to upgrade my expo sdk using npm install expo@latest
and npx expo install --fix
.
The security warnings were gone after this but I started having serious problem when I tried building the android app via Andriod Studio:
I used npx expo start
to start the development environment and selected option a for android build, unfortunately, it keeps failing with the following errors:
TypeError: Cannot read property 'packagerOpts' of null, js engine: hermes
