Using a Python subprocess in WSL to create an item in a vault hangs when capuring output
I have a python script that I use to batch create items in vault within ubuntu under WSL. Works in general - Creating Vaults, reading items etc. except for creating an item in an existing vault whilst capturing - it hangs in some kind of loop and has to be aborted.
I am calling op.exe because I want to call the windows command line client - we are generally using Microsoft SSO, so you can't use the ubuntu command line client by itself.
- Windows 11
- WSL2
- Description: Ubuntu 24.04 LTS
- 1Password for Windows 8.10.45
- OP command line 2.29.0
- Python 3.12.3
Note that '---' below is the python prompt '>>>' - I couldn't figure out how to escape it.

KeyboardInterrupt
My account doesn't use SSO, so i can set up the Ububtu CLI and use that. Creating items whilst capturing the output works OK
