我正在尝试实现数据管道，在该管道中，我尝试通过DataFlow从那里在PubQ中将json插入BQ。我正在使用模板将数据从PubSub传输到BQ。我的DataFlow失败了。它正在错误流中。但是我看不到该错误的更多详细信息。例如，是否由于pubsub中数据的编码错误而失败，由于架构不匹配等而失败？在哪里可以找到这些详细信息？我正在检查Stackdriver错误和日志，但无法找到更多详细信息。
此外，我可以看到此错误：
resource.type =“ dataflow_step” resource.labels.job_id =“ 2018-07-17_20_36_16-6729875790634111180” logName =“ projects / camel-154800 / logs / dataflow.googleapis.com％2Fworker” 时间戳> =“ 2018-07-18T03：36：17Z”严重性> =“ INFO” resource.labels.step_id =（“ WriteFailedRecords / FailedRecordToTableRow” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / PrepareWrite / ParDo（匿名）” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / CreateTables / ParDo（CreateTables）” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / StreamingWriteTables / ShardTableWrites” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / StreamingWriteTables / TagWithUniqueIds” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / StreamingWriteTables / Reshuffle / Window.Into（）/ Window.Assign” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / StreamingWriteTables / Reshuffle / GroupByKey” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / StreamingWriteTables / Reshuffle / ExpandIterable” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / StreamingWriteTables / GlobalWindow / Window.Assign” 要么 “ WriteFailedRecords / WriteFailedRecordsToBigQuery / StreamingInserts / StreamingWriteTables / StreamingWrite”）
它告诉我它失败了，但是我不知道为什么它失败了？是否存在架构不匹配或数据类型问题或编码错误或什么？如何调试？
