Dependency lockfile seemingly missing in 1.3.0

[xylar]

• Poetry version: 1.3.0
• Python version: 3.10 (but applies to any)
• OS version and name: Any
• pyproject.toml: N/A

• 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.

(I don't have an easy way to do this last one.)

Issue

On conda-forge, we are seeing:

poetry -V
Traceback (most recent call last):

It seems that the lockfile dependency is missing from the pyproject.toml. See our CI for details:
