[BUG] Cannot CTRL-C ray serve when running with doppler

[lukasschmit]

Describe the bug
I am trying to develop using ray serve locally. When I do

doppler run -- serve run test:binding

The process runs but cannot be killed with CTRL-C/D. I have to kill -9 it.

To Reproduce

pip install "ray[serve]"
doppler run -- test:binding # attached

test.py.zip

Expected behavior
I expect the process to be able to be killed normally, but CTRL-C/D are unresponsive.

Screenshots

Desktop (please complete the following information):

• OS: macOS 13.2.1 (M2 MAX 16" MBP)
• Version [e.g. 10.15.1]

CLI Version:

doppler --version
v3.56.2

Could you try this again with the --forward-signals flag? i.e. doppler run --forward-signals -- serve run test:binding
