I've encountered a head scratcher. I have an example repo where I am able to debug without issue, in visual studio, using

./pants test --debug-adapter path/to/target:test

and a remote attach configuration in VSCode. Break points are hit, code is mapped properly. In our company repo, I have integrated pants and tried to use exactly the same configuration but I encounter an error. Any insight as to what is missing? This is the console log. After

Launching debug adapter at '127.0.0.1:5678', which will wait for a client connection...

I execute the vsCode remote attach configuration and receive a

KeyError: 'console_scripts'

> ./pants test --debug-adapter realtime/tests/test_eeg_processor.py

I have to run an errand so I'll be out for about an hour. Thanks in advance for your help!

What version is this? I recently fixed a handful of debug adapter issues

I'm using

2.14.0

and tried

2.15.0rc0

as well but the problem persists.

It would be in rc1 when released

Hot sauce! I tried

2.16.0.dev3

and the breakpoints do their thing. I will try

2.15.x

sha and report back. Thanks for fixing it before I found it 😉

No, that's on us. Feel free to open an issue
