Python: Python AG-UI Magentic TEXT_MESSAGE_END emmitted after RUN_FINISHED when plan review is enabled and resume payload has empty review list

[dgsear]

When using magentic orchestration withb plan review feedback enabled , sending a plan review resume request with empty feedback review:[] , stream emits RUN_FINISHED first , then later emits TEXT_MESSAGE_END for the same run, causing INCOMPLETE STREAM errors when copilotkit consumes them.

Observed behaviour
RUN ERROR with message Cannot send 'RUN_FINISHED 'while test messages are still active with code "INCOMPLETE STREAM" from copilotkit.

observed Event order
1.RUN_STARTED
2.TEXT_MESSAGE_START
3.TEXT_MESSAGE_CONTENT
4.RUN_FINISHED with no interrupts
5.TEXT_END

Env tested on
agent-framework-ag-ui= 1.0.0

Could you pls confirm whether its a known issue and already fixed in recent releases

• Fixed in [BREAKING] Python: Allow workflow checkpoint full replayability #7374, which closes any open text message before the terminal event so RUN_FINISHED is always last. Released in agent-framework-ag-ui 1.0.1; 1.0.0 predates it.
• Separately, Python: Fix AG-UI resume rejecting JSON for typed responses #7684 (in 1.1.0) added JSON→dataclass coercion for workflow resume payloads, which is what maps a raw {"review": []} onto MagenticPlanReviewResponse. Also not in 1.0.0.

Upgrading to 1.1.0 picks up both. That should clear the INCOMPLETE STREAM errors on the CopilotKit side.

👋 Hi dgsear — thanks for the report!

Your reported agent-framework-ag-ui==1.0.0 predates commit 0e6a1041923b4351f0a1756ff1551f3e58ad7532, which closes active text messages before RUN_FINISHED. Current code emits TEXT_MESSAGE_END followed by RUN_FINISHED, and also accepts the raw {"review": []} payload after #7684. Upgrading to 1.1.0 or newer should address both behaviors.

• You reported using: 1.0.0
• Latest version: 1.2.0
• Likely fix: 0e6a1041923b

If upgrading to the latest release doesn't fix it, please reopen and we'll take another look. 🙏

Current code closes text messages before RUN_FINISHED; relevant changes merged in #7374.
