[adrien-fichet]

• Package Name: appconfiguration
• Package Version: 1.7.2 or 1.7.3
• Operating System: MacOS
• Python Version: Python 3.14

Describe the bug
There is an invalid escape sequence \ in the auto-generated file appconfiguration/_generated/models/_models.py (line 238), which gives the following warning:

SyntaxWarning: "\ " is an invalid escape sequence. Such sequences will not work in the future. Did you mean "\\ "? A raw string is also an option.
  """An error, available when the status is ``Failed``\ , describing why the operation

To Reproduce
Steps to reproduce the behavior:

1. Install the azure-appconfiguration package for the first time
2. Run any code containing an import from azure.appconfiguration

Expected behavior
There should be no invalid sequence in the files generated by autorest.

This seems to be an issue with the code that does the auto gen, i'm not even sure why the \ is present.

API Spec: https://github.com/Azure/azure-rest-api-specs/blob/1360de669e7a0eca58314dec87f2a3e1605e77de/specification/appconfiguration/data-plane/AppConfiguration/models.tsp#L325
Issue:

azure-sdk-for-python/sdk/appconfiguration/azure-appconfiguration/azure/appconfiguration/_generated/models/_models.py

Line 238 in ca2b965

"""An error, available when the status is ``Failed``\ , describing why the operation

The same line is on 227 and that was generated in a valid way, but also shouldn't have the \\ it is not in our api spec.

I'm following up with the gen team on this.

@adrien-fichet what operation did you run to get this issue. I use the standard pip to install but never see the warning come up.

The warning can be seen when the azure-appconfiguration bytecode is not compiled yet (so when no __pycache__ directories are present). That's the default behaviour when using uv to install dependencies and that's how I encountered the problem.

However, pip does compile bytecode by default when installing dependencies, so I guess that's why you don't see the warning. The steps to reproduce the issue on a fresh venv, with pip option -no-compile are as follow:

python3 -m venv .
source bin/activate
pip install --no-compile azure-appconfiguration
python3 -c "from azure.appconfiguration import AzureAppConfigurationClient"
