Hey,

In your example, "~/Documents/tool/tejia_analysis" is your module's source root, right? Could you show where "app_server/util/analysis.go" is on the FS and what is the name of the module?

pprof has a coupe flags to manipulate with the path, helping it to search for the source code. I used to use the combination of "-source_path" and "-trim_path" to map my local source code to the paths that were embedded into the app's binary.

se the combination of "-source_path" and "-trim_path"  still not work
