ChildProcessManager::setupEventHandlers | Child process stderr: AssertionError [ForgeAgentError]: Mu
What Happened#
2026-05-27 09:17:56 UTC에 cupixworks-any-bimrevision-agent 서비스에서 BIM revision 비교 작업 중 ForgeAgentError (code 514)가 발생했다. @cupix/forge-agents 패키지의 EntityMap.load() 메서드가 Forge manifest에서 modelId 11에 해당하는 SVF derivative를 찾지 못해 assertion failure가 발생하고, 이것이 critical error로 분류되어 전체 revision 비교 작업이 중단되었다.
