When executing

poetry publish --build -r internal -u ${ARTIFACTORY_USER} -p ${ARTIFACTORY_PASS} -vvv

I got this:

Ok. I was able to work around this by removing ‘simple’ from the path per this post: https://github.com/python-poetry/poetry/issues/708

some app ‘bar’ notice the url does not have `/simple here’

poetry config repositories.foo https://artifactory.foo.com/artifactory/api/pypi/pypi-shared/
poetry publish --build -r foo

then in a dependent project, I can add this library via poetry

notice that the url ends with /simple here

//pyproject.toml

[[tool.poetry.source]]
name = "artifactory"
url = "https://artifactory/api/pypi/local-pypi/simple"

$ poetry add bar

I’m getting the same error as well on Poetry 1.0.5. Trying to publish to Artifactory v5.3.0 rev 50045.

HTTP Error 500: Internal Server Error

I have no access to server side logs to provide.

EDIT: I printed out the Requests POST response in poetry/masonry/publishing/uploader.py and it provided the 500 error: No enum constant org.jfrog.repomd.pypi.model.PypiMetadata.MetadataVersion.v2_1

Older versions of Artifactory are affected by this issue, resolved in v6.1.0. https://www.jfrog.com/jira/browse/RTFACT-16189
