Relay stopped working; `ReferenceError: targetUri is not defined` error with AP Announce activity into inbox

[ltlapy]

💡 Summary

AP Inbox 로 들어오는 Announce activity가 ReferenceError: targetUri is not defined 오류와 함께 처리되지 않는 문제가 발생하고 있습니다. 릴레이가 게시물의 전파에 announce 액티비티를 사용하는 만큼, 릴레이로부터 오는 연합을 받지 못하고 inbox 큐가 쌓이고 있습니다.

🥰 Expected Behavior

Announce activity is accepted without problem

🤬 Actual Behavior

ReferenceError: targetUri is not defined
