AttributeError: 'AgentState' object has no attribute 'state' AND other weird behavior

[NovaBro]

Describe the bug

1. When I run "letta run" and select a previous agent through the CLI, I get the error "AttributeError: 'AgentState' object has no attribute 'state'"
2. When I create an agent through the CLI, I cannot find it on the ADE. When I create an agent on the ADE, I cannot see it through the CLI

Please describe your setup

Installation

1. I have created a python 3.12 virtual environment
2. I then did pip install letta
3. Followed the quickstart guide

Setup

1. macOS 14.6.1, m1 chip,
2. VSCODE
3. Running letta though terminal
4. Tried running the python stuff mentioned, but that has not worked for me either, (i assume that once this issue is fixed the python stuff will then work, one problem at a time)

Screenshots If applicable, add screenshots to help explain your problem. letta not showing up on both systems:

Local LLM details Unsure how to find the following information, if you need them please advise on how to get them:

• [ ] The exact model you're trying to use (e.g. dolphin-2.1-mistral-7b.Q6_K.gguf)
• [ ] The local LLM backend you are using (web UI? LM Studio?)
• [ ] Your hardware for the local LLM backend (local computer? operating system? remote RunPod?)
