AWSPuml Entity objects will not generate a preview (produces an error)

[cfGenesys]

Attempting to run https://github.com/awslabs/aws-icons-for-plantuml?tab=readme-ov-file#hello-world the following error below is produced. The error seems to relate to using the entity instead of the participant; that is if WorkDocs, and SimpleStorageService are change to WorkDocsParticipant and SimpleStorageServiceParticipant the plugin will generate a preview. Others seem to be having a similar issue: awslabs/aws-icons-for-plantuml#66.
I was able to use the hello-world in both the plantUML online server and the installed version with now issue.

Hi @cfGenesys, and all,

• Is dot is installed on your system?
• Could you test the same example but without dot GraphViz?

@startuml Hello World
!pragma layout smetana

' Uncomment the line below for "dark mode" styling
'!$AWS_DARK = true

!include <awslib/AWSCommon.puml>
!include <awslib/BusinessApplications/all.puml>
!include <awslib/Storage/SimpleStorageService.puml>

actor "Person" as personAlias
WorkDocs(desktopAlias, "Label", "Technology", "Optional Description")
SimpleStorageService(storageAlias, "Label", "Technology", "Optional Description")

personAlias --> desktopAlias
desktopAlias --> storageAlias

If that can help,
