java.lang.IllegalStateException : Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 7770 path $. 电影[8].images.poster

Question

我收到错误java.lang.IllegalStateException:预期为 BEGIN_OBJECT，但在第 1 行第 7770 列路径 $.films[8].images.poster 处为 BEGIN_ARRAY当我尝试返回电影列表时。该应用程序工作正常，直到昨天我来测试它时，它现在抛出此错误。自从超出限制后，我没有更改任何代码，只更改了 API 凭据。
