Error Summary

Bot pod flexus-pod-bot-karen-100020189-rx in namespace isolated crashloops on every startup because the backend GraphQL schema no longer has news_payload_task on FBotThreadsCallsTasks.

Stacktrace

TransportQueryError: Cannot query field 'news_payload_task' on type 'FBotThreadsCallsTasks'

Root Cause

• File: flexus_client_kit/ckit_bot_exec.py:412
• Function: subscribe_and_produce_callbacks
• Why: the client subscription still asks for a removed field name, while the backend exposes news_payload_task_new, news_payload_task_old, etc.
• Git blame: see gql_utils.py / subscription helpers; schema mismatch is in the client kit path

Code Snippet

        logger.exception("3 exceptions in 5 min, exiting")
        raise

Affected

• Pods: flexus-pod-bot-karen-100020189-rx
