Disable minification during builds in Next 15

Currently running into an issue where I'm getting an Application Error, but only when building and deployed to prod/stage in our project. This wouldn't be a problem, but nobody can replicate the error in dev with npm run dev or by building and doing npm run start. So we just have this nebulous minified error in prod/stage. It's https://react.dev/errors/185, but of course we get no real details.

There used to be a way to disable minification by putting swcMinify: false in next.config.mjs, but it seems like this was disabled in Next 15 for some reason. I've tries using swcrc.json to disable minificaiton, but this didn't work. I'm not sure Next reads from here for swc. I've been searching high and low for a solution, but I can't seem to find a way to disable minification to figure out what this error is.

Is there any way to disable minification in Next 15? Or does anyone have any suggestions on how to debug this issue?

Thanks!

You cannot do that as of next.js 15
but I doubt it's what's causing your bug

You're correct, its not causing the bug.

But the bug only appears in the built version of the app. I'd like to disable minification in my build so I can get more detailed error information instead of a minification error.
