Amazon web services AWS CodePipeline-工件文件权限被拒绝

有yaml/json问题，错误如下。没有更改AWS代码管道中负责生成工件的行，但它会抛出如下错误

不知道发生了什么错误以及它抛出

权限被拒绝的原因是什么？？？有人遇到过这样的错误吗

编辑：昨天晚上工作得很好。。。没有变化

Running command build/codebuild/imagedefinitions-prod-celery.json 

这似乎是一个无效的命令：

build/codebuild/imagedefinitions-prod-celery.json 

如果找到命令但该命令不可执行，则返回状态为126

请检查buildspec中的命令。
是的，我今天似乎在添加一些东西，但忘了完成。非常感谢。
