Python 弹性转码器

当我试图使用通过python函数Boto3从Lambda调用的弹性代码转换器时，我犯了以下错误。Cloudwatch日志中的错误是：“调用CreateJob操作时发生错误（ValidationException）：检测到1个验证错误：“pipelineId”处的值“PIPE”无法满足约束：成员必须满足正则表达式模式：^\d{13}-\w{6}$”

根据我的代码，我在Elastic Transcoder中将管道ID的名称指定为管道，它不喜欢使用的字符。我尝试过其他一些组合，比如数字和点。以前有人犯过这个错误并解决过吗？我使用AWS示例代码作为起点。提前谢谢

我认为您的管道id应采用以下格式：

1704334089176-jhNzi6（13位数字后跟一个“-”，后跟6个字母数字字符）

请在弹性转码器中检查管道ID，以确认正确的管道ID。也许这可以帮助您找到正确的ID：

为什么要将PipelineId设置为“管道”？管道ID不是您选择的标识符；它是一个现有管道资源的ID，您以前应该使用该资源或等效资源创建它，并且弹性代码转换服务为它分配了一个唯一的管道ID，其形式为

^\d{13}-\w{6}$

谢谢！我已更新代码，以包含管道id而不是名称。
