Failed to access Docker

[patrickacraig]

When I start LangGraph Studio, I am getting the following error notification:

Failed to access Docker: Unexpected token 'j', "json" is not valid JSON

I have reinstalled Docker and LangGraph Studio, but the issue persists. Note that this error occurs before attempting to open any particular folder.

Any ideas on how to troubleshoot/fix would be greatly appreciated.

Hello @patrickacraig! Could you share the output of docker info -f json or docker info?

@dqbd that was for docker info -f json. Let me know if that's not the output you were looking for.

Update on this: Installing the Docker CLI tools separately using Homebrew fixed the error. If you encounter the error above, just run brew install docker docker-compose docker-machine in your terminal, then run brew services start docker-machine and restart Docker Desktop and LangGraph Studio and you should be good to go.

Just worked for me after I updated my Docker Desktop version
