this is such an amazing video . I wanted to know general things and the capabilities of sam and this helped a lot!

This video is very informative! Well done 👌

This is a great video, Nikhil. Really appreciate the effort you've put in to create these. Thanks!

Some questions I had:
– Should I check-in the `.aws-sam` or does it makes more sense to keep it in gitignore?

hi sir am very new to sam cli can you let me know if you have a video for post api using python

[lazarivic]

i have the problem saying : ' Stack aws-sam-cli-managed-default is missing Tags and/or Outputs information and therefore not in a healthy state (Current Failing as the stack was likely not created by the AWS SAM CLI
' when i try to deploy
could you maybe explain what went wrong

[AdrianGood]

Not a fan of dishing out full admin. I was able to deploy this stack using the following IAM policies attached to my programatic user:
- AWSLambdaFullAccess
-
- AWSCloudFormationFullAccess
- IAMFullAccess

Perhaps its still to much or not enough privilege, but still much tighter than full admin. Just need to remember to grant the appropriate policies as you develop and add other AWS components such as S3/SNS/SQS etc.

Thanks for the Vid

How can I create only APIs in SAM template because my application required only APIs which will be called by mobile devices

[VikramKumar-obef]

facing issue while building the artifact when i run command sam build, expection: Stack object has no attribute 'Resources'

[RizwanAli-kibx]

Really great tutorial, Please let me know how and where we can define multiple functions. Is it app.py where have to define all of our functions?

[productprinting]

Can you please tell what are the exact permissions required for SAM to function properly?

The video is great however, I ran into a little problem following it towards the end and was getting the message below:

I have also tried creating new credentials for the test user and using those key pairs but got the same thing
