Ошибка при опустошении массива в качестве струнного JSON в массив объектов с Springai ⇐ JAVA

[Anonymous]

Я использую Spring.ai и использую структурированные выходы, и в настоящее время он выводит для меня массив объектов в строковой форме, но я получаю приведенную ниже ошибку, и я не слишком уверен, почему. Я пытался преобразовать строку в объект, который ее соответствует, но она не работает.

Какой набор тестового набора печатает json.{"tests":[{"code":"int arr[] = {0, 5, 10, 15};\nint result = CountBetween(arr, 4, 3, 12);\nprintf(\"%d\", result);","expectedStdOut":"2"},{"code":"int arr[] = {0, 5, 10, 15};\nint result = CountBetween(arr, 4, 12, 3);\nprintf(\"%d\", result);","expectedStdOut":"2"},{"code":"int arr[] = {3, 12, 6, 9};\nint result = CountBetween(arr, 4, 3, 12);\nprintf(\"%d\", result);","expectedStdOut":"2"},{"code":"int arr[] = {4, 4, 4, 4};\nint result = CountBetween(arr, 4, 1, 5);\nprintf(\"%d\", result);","expectedStdOut":"4"},{"code":"int arr[] = {1, 2, 3};\nint result = CountBetween(arr, 0, 0, 10);\nprintf(\"%d\", result);","expectedStdOut":"0"},{"code":"int arr[] = {1, 2, 3};\nint result = CountBetween(arr, -5, 0, 10);\nprintf(\"%d\", result);","expectedStdOut":"0"},{"code":"int arr[] = {1, 2, 3};\nint result = CountBetween(arr, 3, 5, 5);\nprintf(\"%d\", result);","expectedStdOut":"0"},{"code":"int arr[] = {INT_MIN, INT_MIN + 1, 0, INT_MAX - 1, INT_MAX};\nint result = CountBetween(arr, 5, INT_MIN, INT_MAX);\nprintf(\"%d\", result);","expectedStdOut":"3"},{"code":"int result = CountBetween(NULL, 0, 0, 10);\nprintf(\"%d\", result);","expectedStdOut":"0"},{"code":"int result = CountBetween(NULL, 5, 0, 10);\nprintf(\"%d\", result);","expectedStdOut":"0"}]}
