Unexpected Token Errors with expo start after upgrading Expo

[askpatrickw]

Description

After following the upgrade steps from 27.0 -> 28.0 -> 29.0 -> 30.0 I get an error when I try to run my app on android emulator. The error ocurrs at each step (i.e. it happened at 28.0 but I decided to keep going)

I did blow away node_modules and npm install.
I launched with expo start -c

NOTE: When I run expo build:android the resulting APK can be side loaded and runs fine.
I suspect there is more to be cleaned up when doing upgrades which is not documented.

Expected Behavior

App should run fine.

Observed Behavior

What actually happened when you performed the above actions?
