왜 이 오류가 내 포럼에서 계속 발생하나요? 무시해도 안전한가요?

Job exception: PG::UniqueViolation: ERROR:  duplicate key value violates unique constraint "index_users_on_username"

훨씬 더 많은 컨텍스트가 필요합니다. 백트레이스는 무엇이고, env에는 어떤 것이 포함되어 있나요?

관련이 있는지 없는지는 모르겠어요. 저는 API를 통해 사용자를 등록합니다. 사용자에게 사용자 이름을 받아서 API로 해당 사용자 이름이 존재하는지 확인하고, 존재하면 Discourse가 제안하는 이름을 선택합니다. 그런데 제안된 이름이 실제로는 어딘가 깨진 상태의 기존 사용자 이름인 경우가 많아요. 즉, 해당 사용자의 프로필을 확인하려고 하면 ‘찾을 수 없음’ 오류 페이지가 표시됩니다.

참고로, 이 깨진 사용자 문제는 다음 링크에서 보고했습니다:
