How to list object using delimeter and sort_by in aws s3 api?



I used below command to list object using delimeter to print second level folder only -



aws s3api list-objects-v2 --bucket $bucketNameToUse --prefix $prefixToUse --output text --delimiter "/"
COMMONPREFIXES firstlevelfolder1/
COMMONPREFIXES firstlevelfolder2/


It worked fine and print second level folders based on prefix that I passed.



And I used below command to list the objects based on last modified date.



aws s3api list-objects-v2 --bucket $bucketNameToUse --prefix $prefixToUse --output text --query 'sort_by(Contents,&LastModified)[*].[Key,LastModified]'
firstlevelfolder1/ 2018-12-28T11:41:07.000Z
firstlevelfolder2/ 2018-12-28T11:41:18.000Z
firstlevelfolder1/secondlevelfolder1/ 2018-12-28T11:41:30.000Z
firstlevelfolder2/secondlevelfolder2/ 2018-12-28T11:41:43.000Z
firstlevelfolder1/secondlevelfolder1/test.java 2018-12-28T11:42:28.000Z
firstlevelfolder2/secondlevelfolder2/test.java 2018-12-28T11:42:46.000Z


it worked fine and print the objects sorted by time.



But when I tried to combine both the command I got error -



aws s3api list-objects-v2 --bucket $bucketNameToUse --prefix $prefixToUse --output text --query 'sort_by(Contents,&LastModified)[*].[Key,LastModified]' --delimiter "/"

In function sort_by(), invalid type for value: None, expected one of: ['array'], received: "null"

          Your command is probably returning 0 objects (None value here) but the sort_by method will expect an array



          Check if this returns objects or not:
          aws s3api list-objects-v2 --bucket $bucketNameToUse --prefix $prefixToUse --output text --delimiter "/"



          If this does not then that's your issue.

          • Thanks for checking on my question @sanster_23, the command given by you is same which I used in my question and it prints the result and the second command that I used without delimeter also worked fine to sort the objects but when I used delimiter and sort_by it didn't work.

          • @VIPINKUMAR when you get only folders in the list that means - you have a list of object prefixes like (f1/, f2/) etc. these do not have a LastModified field. only Objects do.
