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

I am receiving the error
java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 7770 path $.films[8].images.poster
when I try to return a list of films. The application was working fine till yesterday when I came to test it, it now throws this error. I hadn't changed any of the code since only the API credentials since I went over the limit.

As she prepares for the show, battles with management, charms musicians and reminisces with friends and adoring fans, her wit and warmth shine through. Even her dreams of love seem undimmed as she embarks on a whirlwind romance with Mickey Deans, her soon-to-be fifth husband.

While the young Emperor Nero must battle his scheming mother Agrippina for ultimate power, Celt queen Boudicca gathers an army in Britain to repel the rotten Romans. Mixed up in this battle for liberation are the teenage Atti, a reluctant Roman soldier, and Orla, a young Celt with dreams of becoming a warrior like Boudicca. Will they fall on opposite sides or forge a friendship in the chaos of Celtic-inspired rebellion?",
