Failed to deploy: Automatic rollback disabled for this deployment

Question

I am trying to run Deploy multiple machine learning models for inference on AWS Lambda and Amazon EFS, I have done all the steps correctly, however, when I use the sam build --use-container command, I was falling into memory error.

In order to solve this problem I resizing EBS volume manually to 30 Gib and I used the sam build --debug --use-container command because I realized that cloud9 and my runtime had different versions of python.

After much research and trying I was able to build it successfully. But, when I went to deploy, using the command sam deploy --guided, I got the following:

Error: Failed to create/update the stack: sam4-app, Waiter StackCreateComplete failed: Waiter encountered a terminal failure state: For expression "Stacks[].StackStatus" we matched expected path: "ROLLBACK_COMPLETE" at least once

Researching about this error, I noticed that it is a problem with the lambda function. When I access Applications in the AWS Lambda it shows a creation error.

I tried various solutions like directly specifying the s3 bucket, using another version of sam, I tried running the MLInference-Lambda-EFS code, but nothing works.

Does anyone know how I can solve this problem? I have been struggling with this project for a long time.

Answer 1

Please run sam delete --stack-name aws-sam-cli-managed-default to remove the broken managed stack before going through guided deploy or --resolve-s3 again.

I ran the deploy command again sam deploy --s3-bucket test-bucket --guided and it worked when I specified a bucket name. This bucket is ignored by SAM and the stack is created without problem.
