@throrin19: I had the same problem and according to your serverless.yml, it might be caused by the same cause.

I have noticed, you are also using a custom variable to store your AccountId and it also starts with a 0. Can you try wrapping your AccountId value in single quotes? accountId : '0123456789345'

I believe the value gets interpreted as a number, and all the leading zeroes gets removed. You can also confirm it when inspecting the final CloudFormation template which should be a part of your ServerlessDeploymentBucket.

@pgrzesik haha it’s seems the same. My account ID start with 0
