Unable to describe_recovery_snapshots (drs) based on date range

[mmilanetti]

Folks,

Trying to describe DRS recovery snapshots like this works just fine:

`

import boto3
from datetime import datetime, timedelta

def list_recovery_snapshots(source_server):
	
	drs_client = boto3.client('drs', region_name = 'us-west-2')

	response = drs_client.describe_recovery_snapshots(
		maxResults=4,
		order='DESC',
		sourceServerID=source_server
	)    
	
	for item in response['items']:
		print(item)

if __name__ == "__main__":
	
	source_server = 's-54139f2c8246ace91'
	list_recovery_snapshots(source_server)`

This works, it results in an output with the recovery snapshots.

However, I've been unable to make it work with a filter for fromDateTime and toDateTime:

`

import boto3
from datetime import datetime, timedelta


def list_recovery_snapshots(source_server):
	
	drs_client = boto3.client('drs', region_name = 'us-west-2')

	end_dt   = datetime.now()
	start_dt = end_dt - timedelta(days=3)
	end_dt   = end_dt.strftime('%FT%T')
	start_dt = start_dt.strftime('%FT%T')

	print('Start date: ' + start_dt)
	print('End date: ' + end_dt)

	response = drs_client.describe_recovery_snapshots(
		filters={
			'fromDateTime': start_dt,
			'toDateTime': end_dt
		},
		maxResults=4,
		order='DESC',
		sourceServerID=source_server
	)    
	
	for item in response['items']:
		print(item)
		continue


if __name__ == "__main__":
	
	source_server = 's-54139f2c8246ace91'
	list_recovery_snapshots(source_server)

`

Output:

Start date: 2023-05-07T22:46:26 End date: 2023-05-10T22:46:26

Exception:

Exception Exception has occurred: ClientError An error occurred (BadRequestException) when calling the DescribeRecoverySnapshots operation: Invalid request body File "/home/ec2-user/LocalDev/DRS-Drill/lambda/test.py", line 20, in list_recovery_snapshots sourceServerID=source_server File "/home/ec2-user/LocalDev/DRS-Drill/lambda/test.py", line 31, in <module> list_recovery_snapshots(source_server) botocore.exceptions.ClientError: An error occurred (BadRequestException) when calling the DescribeRecoverySnapshots operation: Invalid request body

Documentation says the from and to dates are string values.
I've tried different formats, like ('%F %T') or simply converting the dates got from datetime module to string, no luck.

Any help would be appreciated. Thanks!

Hi @mmilanetti, thanks for reaching out. Looking at the regex mentioned in the documentation, it looks like it's expecting a 'Z' with an optional decimal value at the end of your dates.

2023-05-07T22:46:26Z
2023-05-07T22:46:26.1Z

Both of those match the regex it's asking for. Could you give that a try, and if it doesn't work, provide debug logs (boto3.set_stream_logger('') and redact sensitive information)? Thanks!

That was it @RyanFitzSimmonsAK, I missed that 'Z'. Thanks a lot for pointing that out!
