當我嘗試在數據庫中創建新實體時，出現錯誤「無法使用類型爲Symfony \ Component \ Form \ FormRenderer的對象作爲數組」我的奏鳴曲管理包與Symfony。我之前沒有這個問題，並且我沒有更改管理文件中的任何內容。錯誤500 SonataAdmin：無法使用Symfony Component Form FormRenderer類型的對象作爲數組

Ca你分享團隊實體嗎？它看起來像你的一個字段是一個數組，你試圖以非數組字段類型進行渲染。逐個評論你的每個領域，你會發現哪一個是失敗的。 – albert
¿您能在錯誤日誌或錯誤頁面中檢測錯誤行嗎？ – Cuchu
@albert感謝您的幫助，我更新了與團隊實體的問題 – Makhtar
