Hi, I am having issue with an app that has been deployed many times and was successful 90% of the times. Yesterday I made some update to 4 files in my app, after I deployed I got a blank screen.

Console Error

Uncaught ReferenceError: job is not defined

at index-vlGY8UlG.js:246:15602

Troubleshooting Steps Taken

Same deployment worked 2-3 days ago, now shows blank screen

Error: Uncaught ReferenceError: job is not defined

Cleared all external data sources (Clerk, Neon, browser cache) still blank screen and same console and network output

Even old working deployments now fail with blank screen

I restored code from backup, but same issue
