ValueError: Missing required config key 'store' for conditional edge
Cause
LangGraph does not inject the store dependency into conditional edge functions the way it does for nodes, so an edge function declaring a store parameter receives no value at runtime.
Fix
Remove the store parameter from the conditional edge function. Access store data inside a preceding regular node and pass the result through state instead. Track the upstream fix in LangGraph PR #6425 targeting v1.1.
