Installation of packages fails

[Jas2Ma]

• Poetry version: 1.2.1
• Python version: 3.8.14
• OS version and name: docker: image python3.8
• pyproject.toml: https://gist.github.com/Jas2Ma/3e5a49da3b4a56e98078e12279f3895d/raw/be6afc7aac783fc2567b994e682c5c70e715f20d/pyprojekt.toml

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

Rerunning my gitlab-ci pipeline it fails since 1.2.1, with 1.2.0 it worked.

Here is the debug -vvv output:

There's an invalid constraint somewhere in your dependency tree. poetry-core had a bug where this was accidentally cast to the any constraint (*) when read, which was fixed in the latest core release. The diagnostics here definitely should be better/contain context to help understand what is causing this error -- however I don't think this is a bug in Poetry.

Poetry recently had this exact issue in its own constraints: see #6402 for details.

You should try re-locking to make sure a newer dep doesn't solve the bad constraint issue -- however as I can install your pyproject.toml just fine (minus the redacted repos), I suspect the problem lies in a private dependency and you should check the syntax of every constraint in those private deps for errors/non-compliance. If you need guidance past that I would suggest reaching out on Discord where you can privately share details of these proprietary dependencies with Poetry team members.

re-locking fixed the issue.
