Trouble with Poetry Operations for a Project Dependent on FastAPI-Cache (commit # 8f0920d , dependency redis)

[SudeshnaBora]

I'm working on a project and have specified a dependency in the pyproject.toml file as follows:

[tool.poetry.dependencies]
fastapi-cache2 = {extras = ["redis"], git = "https://github.com/long2ice/fastapi-cache.git", rev = "8f0920d"}

When I run poetry install, it completes successfully. However, attempting to run poetry lock, poetry add "fastapi-cache2[redis]@git+https://github.com/long2ice/fastapi-cache.git#8f0920d", or poetry update <any-other-dependency> results in failures. The error message indicates a CalledProcessError, mentioning that a subprocess command returned a non-zero exit status:

CalledProcessError
  Command '['/path/to/.venv/bin/python', '-']' returned non-zero exit status 1.
  at /path/to/python3.11/subprocess.py:569 in run

Further details from the error suggest an EnvCommandError, indicating an issue with executing a command in the environment:

EnvCommandError
  Command ['/path/to/.venv/bin/python', '-'] errored with the following return code 1
  Output:
  Traceback (most recent call last):
    ...
    raise BuildException(f'Source {srcdir} does not appear to be a Python project: no pyproject.toml or setup.py')
  build.BuildException: Source /path/to/cache/pypoetry/virtualenvs/project-py3.11/src/fastapi-cache does not appear to be a Python project: no pyproject.toml or setup.py

I attempted to replicate this in a fresh poetry project using the poetry add "fastapi-cache2[redis]@git+https://github.com/long2ice/fastapi-cache.git#8f0920d" command, but encountered a different issue:

Failed to clone https://github.com/long2ice/fastapi-cache.git at '8f0920d', verify ref exists on remote.

I've confirmed that the specific commit 8f0920d indeed contains a pyproject.toml file.

Cloning the project and checking out this commit works fine outside of Poetry, which suggests there may be a bug within Poetry or the way it interacts with this specific git dependency.
