All routes don't compile with next 15.3.1 ...

[CaptainN]

Summary

Basically, every single non-page "route" handler (that is, api route in app router - these labels make it impossible...) stopped"generating" in my very large app. The error I get is completely incomprehensible, pointing to some chunk line-of-code, in the compiled state. Utterly useless. I can work around this by making my routes dynamic, and eating the performance hit - that seems right. Likely, no one at Vercel gives a crap, since this is using a regular app build, not meant for Vercel or OpenNext.

Anyway - anyone else seeing this type of error? I'm using Sentry, which I suspect has something to do with this (it's mandated, I wouldn't recommend using that thing with next.js.)

Additional information

I'm using next build --experimental-build-mode compile and generate - the errors happen in the generate step. Yes, somehow, after a couple of years, this is still experimental...

Update: Yeah, it was Sentry. I disabled that, and it all started working....

This is just Sentry being an absolute nightmare.
