Sending Report Failed from AWS Codebuild

Hi,

I have a problem with running katalon docker in AWS Codebuild.
I’m using buildspec.yml that has a command to pull katalon docker and run the test.
In the end, the report can’t be send to my email.

Fyi, when i run the test with katalon docker in my local, it goes well.
Is there anything that i need to set in AWS Codebuild?

Thanks
