Eas Update Error: Inconsistent Javascript Engine Configuration

I am using an EAS workflow. My eas-cli version is eas-cli/3.15.1 win32-x64 node-v18.16.0

I am trying to get sentry set up with my expo react native app. I’m stuck on this step:

Expo publish is deprecated, so I was told to use ‘eas update’

However, running ‘eas update’ produces this error.

Error: JavaScript engine configuration is inconsistent between app.json and Android native project.
[expo-cli] In app.json: Hermes is enabled
[expo-cli] In Android native project: Hermes is not enabled

I had initially thought it was a problem because i wasn’t using eas build to build my app, but I was able to get a eas build to work for both ios and android and it didn’t fix the problem. I’m not sure where to go from here, please help however you can! Thanks!
