Parameter validation failed error for creating stack instances with "deployment targets"

[ChaitDevOps]

I'm using service managed permission to create_stack_instances for an OU, filtered by intersection of a list of accounts and when i run the command, it gives me an error, Can someone please tell me what's wrong with my code here?

error via cli

Parameter validation failed: Unknown parameter in DeploymentTargets: "AccountFilterType", must be one of: Accounts, AccountsUrl, OrganizationalUnitIds

error via lambda

[ERROR] ParamValidationError: Parameter validation failed: Unknown parameter in DeploymentTargets: "AccountFilterType", must be one of: Accounts, AccountsUrl, OrganizationalUnitIds

lambda code:

def add_stack_to_stackset(StackSetName, accountid):

 response = CF.create_stack_instances(
     StackSetName=StackSetName,
     DeploymentTargets={
         'OrganizationalUnitIds': ['ou-blah'],
          'Accounts': [accountid],
         'AccountFilterType': 'INTERSECTION'
     },
     Regions=['us-east-1']
 )
 op_id = response['OperationId']
 return op_id

cli code

aws cloudformation create-stack-instances --stack-set-name demo --deployment-targets OrganizationalUnitIds=ou-blah,Accounts=12345,AccountFilterType=INTERSECTION --regions us-east-1

Hi @ChaitDevOps thanks for reaching out. Which versions of the AWS CLI and boto3 are you using? Have you tried updating to the latest versions of those?

If you still see the issue after updating can you share your debug logs (with any sensitive info redacted)? You can get these by adding --debug to a CLI command or boto3.set_stream_logger('') to a boto3 script. Thanks!

Hi @tim-finnigan Thanks for your response. I'm using aws-cli/2.6.3 Python/3.9.11 Darwin/21.6.0 exe/x86_64 prompt/off & i'm using the default version provided by lambda. I don't package it myself. Should i be doing that ?

For installing the AWS CLI we recommend these methods: https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html#getting-started-install-instructions. The latest version is 2.7.33 per the CHANGELOG. To update your version of boto3 in a Lambda layer you can refer to this: https://aws.amazon.com/premiumsupport/knowledge-center/lambda-python-runtime-errors/. As mentioned earlier if you're still running into issues please share your debug logs and we can investigate further. Thanks!

adding boto3 lambda layer with latest version worked for me. Thanks for the suggestion @tim-finnigan
