Add --debug flag to command you are running
Can you delete your .aws-sam
folder and retry?
Also, it will be useful if you can provide an example project we can use to re-produce on our side.
Thank you for your response.
When I delete my .aws-sam folder and retry, I can sam build !
Glad to hear that. .aws-sam
folder should only be edited by SAM CLI, my assumption is an external tool changed or deleted a file which caused this problem.
Resolving this issue now but please let us know if you experience another problem in the future.
