I switched to go modules recently and I can't seem to make pprof recognize the source files. Maybe someone here knows how to?

I tried using the -source_path and -trim_path options but I can't figure it out how to make it work.

Interestingly, typing o in the interactive mode of pprof shows the the trim_path option but not the source_path.

Just to be sure: pprof does work with local modules and showing their sources in the stack traces, right?

It does work, I just figured it out.

You need to use both -trim_path and -source_path together.

-source_path should be set to the absolute path to your source code.

-trim_path should be set to the path that go tool pprof is saying the code should be at.

So if pprof is saying the path does not exist at /abc/your/code/main.go then set the trim path to /abc/your/code/ make sure that the -source_path contains the main.go though.
