Issue

I have a CI/CD that use serverless and usePoetry: True, just 3 days ago it was working. But right now it's failing.

Error:
Error: `poetry export --without-hashes -f requirements.txt -o requirements.txt --with-credentials` Exited with code 1

poetry -vvv export --without-hashes -f requirements.txt -o requirements.txt --with-credentials

Here's the -vvv Result

You forgot to provide a way to reproduce the problem, no-one can do anything with this

[dimbleby]

presumably fixed by python-poetry/poetry-core#466

[neersighted]

Closing as there is no reproduction.
