A developer encountered unexpected token costs and slow run times in a LangGraph pipeline, which were eventually traced to an interaction between two independent retry mechanisms. One retry layer was at the step level, while another was an orchestrator recovery edge that would re-invoke subgraphs. This led to a step's retry count exceeding its configured limit because the orchestrator's re-invocations were not coordinated with the step-level retries. By implementing a shared retry budget object, the developer gained visibility into the retry process, identifying that a specific 'resolve' step was consuming most of the budget due to upstream API errors. The issue was ultimately resolved by fixing input normalization, but the instrumentation was crucial for diagnosing the problem. AI
