Expo start fails with Unexpected end of JSON input

I am trying to build an expo project that was previously working and now receiving the error:

Unexpected end of JSON input

I have tried clearing my npm cache, deleting .expo, running on different devices, rolling back git to a version I am sure works but I still receive the error.

The error I am receiving is a single line in the console output (no stack trace or any other data), is there any way to provide more information about the failure?


Hey @campbellmg,

Can you run expo diagnostics and paste the log printed out here?
