批处理作业提交错误“无法处理所有文档”，uris 似乎正确？
我一直在尝试让 Document AI 批量提交正常工作，但遇到了一些困难。我使用 RawDocument 进行单个文件提交，假设我可以迭代我的数据集（27k 图像），但选择批处理，因为它似乎是更合适的技术。
当我运行代码时，我看到错误：“无法处理所有文档”。调试信息的前几行是：
O:17:"Google\Rpc\Status":5:{ s:7:"*代码";i:3;s:10:"*消息";s:32:"无法处理所有文档。"; s:26:"Google\Rpc\Statusdetails"; O:38:"Google\Protobuf\Internal\RepeatedField":4:{ s:49:"Google\Protobuf\Internal\RepeatedFieldcontainer";a:0:{}s:44:"Google\Protobuf\Internal\RepeatedFieldtype";i:11;s:45:"Google\Protobuf\Internal\RepeatedFieldklass ";s:19:"Google\Protobuf\Any";s:52:"Google\Protobuf\Internal\RepeatedFieldlegacy_klass";s:19:"Google\Protobuf\Any";}s:38:"Google\Protobuf\ Internal\Messagedesc";O:35:"Google\Protobuf\Internal\Descriptor":13:{s:46:"Google\Protobuf\Internal\Descriptorfull_name";s:17:"google.rpc.Status";s: 42:"Google\Protobuf\Internal\Descriptorfield";a:3:{i:1;O:40:"Google\Protobuf\Internal\FieldDescriptor":14:{s:46:"Google\Protobuf\Internal\FieldDescriptorname ";s:4:"代码";```
对此错误的支持指出错误的原因是：
gcsUriPrefix 和 gcsOutputConfig.gcsUri 参数需要以 gs:// 开头并以反斜杠字符 (/) 结尾。检查存储桶 URI 的配置。
我没有使用 gcsUriPrefix（应该吗？我的存储桶 > 最大批次限制），但我的 gcsOutputConfig.gcsUri 在这些限制之内。我提供的文件列表给出了文件名（指向右侧存储桶），因此不应有尾部反斜杠。
欢迎咨询
