【问题描述】:
当我尝试使用通过 python 函数 Boto3 从 Lambda 调用的 Elastic Transcoder 时,我听到以下错误。 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' 未能满足约束: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 PIPE,它不喜欢使用的字符。我尝试了其他一些组合,例如数字和点。有没有人遇到过这个错误并解决过?我使用 AWS 示例代码作为我的起点。提前致谢!
