Graph cannot generate relationships

[succulen-plants]

🐛 Describe the bug

neo4j 5.25.1
apoc-5.25.1
pip install mem0ai==0.1.34
pip install mem0ai[graph]

My code is as follows

from mem0 import Memory
import os
os.environ['OPENAI_API_KEY'] = '**'
os.environ['OPENAI_BASE_URL'] = '**'
config = {
    "llm": {
    "provider": "openai",
    "config": {
        "model": "gpt-4o-mini",
        "temperature": 0.2,
        "max_tokens": 1500,
        "api_key":'**',
        "openai_base_url":'**'
    }},
    "graph_store": {
        "provider": "neo4j",
        "config": {
            "url": "bolt://localhost:7687",
            "username": "neo4j",
            "password": "**",
            "embedding_model_dims": 1536
        }
    },
    "version": "v1.1"
}
m = Memory.from_config(config_dict=config)
m.add("I like going to hikes", user_id="alice123")

Graph cannot generate relationships：
{'results': [{'memory': 'Likes going to hikes', 'event': 'ADD'}], 'relations': []}

Same issue with me. I have debugged it and found out the tool calling is not working properly
