@Kornspan from the read the docs build:

Installing dependencies from lock file

pyproject.toml changed significantly since poetry.lock was last generated. Run `poetry lock [--no-update]` to fix the lock file.

Seems to be a source of issues on the unit tests as well.

Note that you can run the build process yourself with make docs.

@collindutter I encountered this error while running it on the dev and main branch as well. Do you know what the possible cause might be?

[collindutter]

@galshubeli Are your dependencies up to date? Can you try:

make install/all
make docs

I do get quite a few DeprecationWarnings but you can ignore those.

Separately, I want to apologize for the lack of attention our team has given to this PR. We're definitely interested in incorporating Graph Store Drivers into Griptape and have already started some initial work ourselves. However, we haven't yet fully figured out how they fit into the bigger picture. They will likely play a key role in RagEngine, but we need more time to work through the details.

Given this uncertainty, it's hard for us to provide meaningful feedback on the PR right now. For the time being, it might make sense to close the PR and revisit it once we've solidified our approach. When we're ready, we'd love to get your input on it!

Hey all, I'm going to close this PR for the reasons mentioned above. Once we're ready to support Graph Drivers we'll reach back out!
