Missing sourcemaps for _next/static/chunks/*

[dtbaker]

Hello,

As discussed over here: vercel/next.js#17431

I have connected the app to rollbar and am seeing sourcemaps appear in rollbar, however rollbar is missing sourcemaps for any files under the /_next/static/chunks/* path.

Can you please confirm if this an expected behaviour, or if there's an issue with my setup, or if there might be an issue with which sourcemaps are chosen for uploading?

I'm also having the same issue here. @dtbaker were you able to find a solution or figure out what was the problem?

Digging into my source maps on Rollbar, I noticed that Rollbar claims it can't find the source maps for my chunk files because no sourceMappingURL is found. Isn't the whole point of this plugin to not use the sourceMappingURL comment?

It also says that because the referenced file is not .min.js, it assumes that the file isn't minified. Is there any way we can change this assumption? I haven't found a sane way to make my NextJS files use a .min.js extension and work.

I'm still facing this issue, was anyone able to solve it?

Yeah, I think it's because Next.js build files don't have the extension .min.js, and Rollbar cannot distinguish between them, so it chooses to use the sourcemapURL instead.

The specified file is a source file [is_source_file]
Rollbar interprets files without a .min.js extension as unminified source files, assuming they don’t require a source map. If your file is minified but doesn’t use the .min.js extension, Rollbar might not process its source map correctly.

I'm tired of this shit and will move to Sentry instead
