When using pyproject.toml, package-mode = false can't be used.

The dependencies directory can't be named src.

ValueError: Package name 'src' used in local dep './src' is reserved. Rename the directory.

Is it possible to resolve these two issues?

re: package-mode = false can't be used - how are you triggering that? are you using pyproject.toml with langgraph.json and you have package-mode=false set in the pyproject file?

re: The dependencies directory can't be named src -- see this issue #1308 (comment)

[gbaian10]

I used pyproject.toml and set it up at the top level with Poetry.

[vbarda]

so unfortunately you cannot do that (set package-mode=false or install with --no-root) because we need to install the project itself, not just the dependencies
