產生反應原型鏈誤差原住民可枚舉密鑰

我試着到的base64圖像上傳到火力地堡存儲與和收到此錯誤：產生反應原型鏈誤差原住民可枚舉密鑰

One of the sources for assign has an enumerable key on the prototype chain. Are you trying to assign a prototype property? We don't allow it, as this is an edge case that we do not support.

運行於[email protected]（在V18同樣的問題），並做出反應@ 16.0.0-alpha.12（與世博會v19一起）。
