Issue with Langgraph CLI version 0.0.15 and above on Windows

[KeenanFernandes2000]

I have been using the Langgraph CLI since my issue got resolved in version 0.0.10.

I decided to use the latest version of it being 0.0.17 and it throws an error that doesn't have anything to do with my graphs in particular. I manually tested each version backwards and found this error all the way back from version 0.0.15.

I am using version 0.0.14 which works perfectly, but wanted to bring this to the devs attention.

@KeenanFernandes2000 Thanks for reporting - can you please share a bit more detail about what steps you're taking to trigger the error that you're seeing? What CLI commands are you running? Does it behave this way on any project in your environment, or only specific ones? If specific ones, what is unique about those projects?

I just run the npx command provided on the docs, I guess the same issue still persists in version 0.0.29

Just for reference it works when I use version 0.0.14

Hmm, it's a bit strange that 0.0.14 works but 0.0.17 doesn't. @dqbd would know better than me, but when I do a git diff to find all changes in the langchain-cli directory between 0.0.14 and 0.0.17 I see no changes other than the version number.

We unforunately don't have version tags, but I found the commit hashes - here's the full command:

git diff b7a23ebdabb8fa9deaacdf3e52ec049d74c9d4ae..b7b21f89c441fb7b1f4772dc1a5d5c5d9228be7e -- libs/langgraph-cli

@KeenanFernandes2000 given my previous comment, has anything changed on your end, e.g. tsconfig.json, lockfile bump, etc? Does 0.0.14 still work today and 0.0.17 still fail?

Hello @KeenanFernandes2000! We're now using the @langchain/langgraph version found in your project, so would recommend upgrading the version in your project
