Failed to read project permissions using Python API

[Turribeach]

Hi, I am trying to read project metada using the Python API from outside DSS. This is my code snippet:

import dataikuapi
host = "https://our_dss_instance"
apiKey = "my API key"
client = dataikuapi.DSSClient(host, apiKey)
client._session.verify = False
project = client.get_project("my project key")
project.get_metadata()

The above fails with the following error:

/data/anaconda/lib/python3.6/site-packages/urllib3/connectionpool.py:858: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings

DataikuException: com.dataiku.dip.exceptions.UnauthorizedException: Failed to read project permissions

 I tried with a user API key (which owns the project) and a project API key. Same error. I even tried with a global administrator API and got the same error. Any ideas?

OK I looked at the backend log and found the problem. The error is misleading, there is a second error not shown on the API call error:

Caused by: com.dataiku.dip.server.controllers.NotFoundException: Project does not exist: MyProject

This is due to the project key being case sensitive so I should have used MYPROJECT rather than MyProject. Still it's not very helping that you don't see the actual error in the API call.
