HarmonyOS 鸿蒙Next在arkTS中使用pako进行Gzip解压时报错：incorrect header check

请问，在arkTS中使用pako进行Gzip解压的时候报错：incorrect header check，在线进行解压的时候是正常的，请问是为什么呢？

这是解压前的字符串：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
