Poetry config reports wrong error message when missing values for `poetry config http-basic`

• Poetry version: 1.2.2
• Python version: 3.9.2
• OS version and name:Debian GNU/Linux 11 (bullseye)
• pyproject.toml: Default config after poetry init - see below

• [x] I am on the latest stable Poetry version, installed using a recommended method.
• [x] I have searched the issues of this repo and believe that this is not a duplicate.

• [x] If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

I think the error message for missing credentials in this command could be a little more precise:

$ poetry config http-basic.foo

There is no http-basic.foo setting.

This is especially relevant when using environment variables inside a DOCKERFILE where the variables may be (accidentally) undefined:

$ poetry config http-basic.foo $FOO_NAME $FOO_PASSWORD

There is no http-basic.foo setting.

I've also run into the same problem:while installing Poetry inside a Dockerfile.

RUN poetry source add --secondary myrepo https://pypi.myrepo.com/simple/ && \
    poetry config http-basic.myrepo $POETRY_HTTP_BASIC_PYPI_USERNAME $POETRY_HTTP_BASIC_PYPI_PASSWORD
...
 ---> Running in fe4e7ecce71d
Source with name myrepo already exists. Skipping addition.

There is no http-basic.myrepo setting.

I've added the source two times to make sure that the setting would be there, and still haven't got it to work properly. I'm in Poetry 1.3.1.

Update: the error is not that the setting doesn't exist, it was that the environment variables that I was passing were empty. The error message is misleading. IIRC I saw one ticket that was related to that specific error message around.

@Kircheneer check what's inside your $FOO_NAME and $FOO_PASSWORD variables.

Thank you @ftadao - I had already identified this and it is what I meant to convey with the last part of my original issue.

Oh, sorry! I was thinking that I was posting on another issue related to the error itself. Kinda got a little repetitive there :sweat_smile:

Encountered this today, and decided to skim into the source to find out the cause. I think this could be easily fixed by modifying here - https://github.com/python-poetry/poetry/blob/cdfd955144204c25b277309007c332aaee8be28c/src/poetry/utils/password_manager.py#L200, and not returning an empty HTTPAuthCredential if the username is not found.

I'd like to attempt a fix for this. Could one of the maintainers let me know if I have the right culprit?

@ritabratam-ciq I think your issue might be fixed in #10088. This issue however, seems to be about the error message of the config command.

The comments otherwise are a bit misleading and pointing to another issue (empty or missing password).
