AWS Lambda Trigger on specific subfolder


I created my first AWS Lambda triggered by on file creation on S3 bucket...

This is my bucket (mgdlab-bucket) tree: test-trigger --- sub-folder-1 --- sub-folder-2

I'd like to configure trigger on sub-folder-1 only but it seems not works

Bucket arn: arn:aws:s3:::mgdlab-bucket Event types: s3:ObjectCreated:* Prefix: test-trigger/sub-folder-1

If I upload a new file info sub-folder-2, my lambda is triggered. why?

Does your trigger work if you don't specify any prefix: i..e for the creation of any file in your bucket?

  • Yes. It works without prefix. Probably I need to wait some minutes for changes?
