Describe the Bug
When the application runs inside a Python virtual environment, LocalDevDestinationClient resolves the mocks/destination.json path relative to the SDK's own package directory inside the venv instead of the project root. The documentation states the file should be read from the project root.
I had a look at LocalDevClientBase.__init__ and noticed the path is derived by navigating up three levels from __file__:
repo_root = os.path.abspath(
os.path.join(os.path.dirname(__file__), "..", "..", "..")
)This appears to work when running from a source checkout (where the file sits three levels deep from the project root), but when installed into a venv the package lands at .venv/lib/python3.13/site-packages/sap_cloud_sdk/destination/, so three levels up gives .venv/lib/python3.13/ instead of the project root.
Using os.getcwd() instead would likely fix this, as it resolves to wherever the application is launched from regardless of install location — but you may have other considerations I'm not aware of.
Steps to Reproduce
- Create a project with
mocks/destination.json at the root.
- Set up a Python virtual environment and install
sap_cloud_sdk into it.
- Run the following:
from sap_cloud_sdk.destination import create_client
client = create_client(instance="destination-service")
print(client._file_path)
dest = client.get_instance_destination("my-destination")
print(dest)
- Observe that
_file_path points inside the venv and get_instance_destination() returns None.
Expected Behavior
_file_path should resolve to <project-root>/mocks/destination.json and get_instance_destination() should return the destination defined in that file.

Local mock mode active: using LocalDevDestinationClient backed by mocks/destination.json. This is intended for local development only and must not be used in production.
Note: the log message shows the relative path mocks/destination.json but the client actually resolves it to .venv/lib/python3.13/mocks/destination.json.
