Path issue when src_root and source is in same folder

[pronuba66]

When i'm running with --src_root .
i can only see subfolders and main.c is missing. symbols from main is available in "Show all symbols"
but when i try to access it through http://127.0.0.1:8123/path/main.c/main/ i'm getting "Internal Server Error"

Im able to overcome this by making --src_root ../stack.
Here ../stack/ is the CWD and im able to view main.c but all folders/sources are now absolute paths.

Adding the python logs below
