[Bug] : Error info: The job decomposition result is empty after retry.
environment : macos Python 3.10.18 node.js v22.18.0
I followed the Quickstart.md to build Chat2Graph and opened the web successfully. I added neo4j db which contains some vertex and edge. I try to ask 'tell me the upstream Column of 'val_main' Column', then response :
An error occurred during the execution of the job:
The job fb8966ad-3f40-42e2-a23d-9abe82c7f544 could not be decomposed correctly after retry. Please try again.
Error info: The job decomposition result is empty after retry.
Check the error details in path: '/Users/xxx/.chat2graph/logs/server.log'
Please check the job fb8966ad-3f40-42e2-a23d-9abe82c7f544 ("tell me th...") for more details. Or you can re-try to send your message.

The above logs are printed in a loop. Even when I asked some basic questions, such as "What is a graph?", the same thing happened.
Hi @jiefei30 , I need more information from the server.log (the log information you provided only comes from a Litellm warning, which is a common warning but does not affect the existing project), and I would also like to know what LLM_NAME and LLM_ENDPOINT you are using (make sure your large model configuration is correct). You can curl it?
Follow doc/en-us/deployment/config-env.md or doc/zh-cn/deployment/config-env.md to configure the llm.

Sorry I can't tell you the name of the model (XXX), because this is a private third-party model of our company, but I can guarantee that I can call the model through the postman @Appointat
I think the .env config you are calling Litellm is incorrect. If you are using a private model, you should use the local model invocation method: doc/zh-cn/deployment/config-env.md and https://docs.litellm.ai/docs/providers/vllm (self-hosted mode).
BTW, Chat2Graph calls litellm source code: app/plugin/lite_llm/lite_llm_client.py @jiefei30
