ZEP_API_KEY未配置

Error message

ZEP_API_KEY未配置

What it means

ZepGraphMemoryUpdater.__init__ mirrors the reader's key check: graph_id plus optional api_key, falling back to Config.ZEP_API_KEY; when empty it raises ValueError('ZEP_API_KEY未配置') (note: no space, unlike the reader's message) before building the Zep client and its activity queue. Any simulation started with graph memory enabled will fail at updater construction without the key.

Solutions

1. Provision ZEP_API_KEY (Zep Cloud project key) in the backend's environment and restart.
2. If you did not intend to use graph memory, disable the Zep/graph-memory option in the simulation config so the updater is never constructed.
3. Check for whitespace/quotes around the value in .env — it must be a non-empty string.

Example fix

# before
updater = ZepGraphMemoryUpdater(graph_id="sim_42", simulation_id="sim_42")  # ValueError

# after
# export ZEP_API_KEY=zep_live_xxx  (or set in .env)
updater = ZepGraphMemoryUpdater(graph_id="sim_42", simulation_id="sim_42")
# or explicitly:
updater = ZepGraphMemoryUpdater(graph_id="sim_42", simulation_id="sim_42", api_key=os.environ["ZEP_API_KEY"])

def can_enable_graph_memory() -> bool:
    return bool(Config.ZEP_API_KEY)

try:
    ZepGraphMemoryManager.start_updater(sim_id, graph_id)
except ValueError as e:
    if "ZEP_API_KEY" in str(e):
        disable_graph_memory(sim_id)  # degrade gracefully or fail the start request
        raise HTTPException(400, detail="ZEP_API_KEY required for graph memory")
    raise

When it happens

Trigger: Starting a simulation with graph memory (Zep) enabled while ZEP_API_KEY is unset in the backend process; constructing the updater programmatically without api_key; deploying with a different env file than the one containing the key.

Common situations: Graph-memory feature toggled on before credentials were provisioned; secrets not mounted in container deployments; local dev .env not loaded.
