Php 批量作业(job)提交错误无法处理所有文档，uris 似乎正确

我一直在try 让文档人工智能批量提交工作，但遇到了一些困难.我使用RawDocument提交单个文件，假设我可以迭代我的数据集(27k图像)，但 Select 了Batch，因为它似乎是更合适的技术.

当我运行我的代码时，我看到一个错误:"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"；我:3；S:10:"*消息"；S:32:"所有单据处理失败."； S:26:"谷歌\rpc\状态详情"； 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:"code"；```

support for this error说明错误的原因是:

GcsUriPrefix和gcsOutputConfig.gcsUri参数需要以gs://开头，以反斜杠(/)结尾.判断存储桶URI的配置.

我没有使用gcsUriPrefix(我应该吗？我的存储桶&gt；最大批量限制)，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(指向正确的存储桶)，因此不应该有尾随的反斜杠.

欢迎提出建议
