Hi @RoshmiB thanks for reaching out. The start-automation-execution command corresponds to the StartAutomationExecution API. Therefore the parameter validation is set by the service team. Here is the Target API documentation showing supported formats for reference.

The SSM User Guide does have a section on targeting multiple managed nodes, where it shows send-command as supporting multiple tags. So I'm not sure if start-automation-execution is designed to not support multiple tags, or maybe this is something that needs to be clarified in the documentation.

Since this issue involves a service API which is used across the CLI/SDKs, I'm going to transfer it to our cross-SDK repository. I'll also reach out to the service team to try to get more information. (ref: D77464262)
