SSM sendCommandCommand seems to be missing the executionTimeout parameter

[johnlabarge]

Is your feature request related to a problem? Please describe.

I need to extend the timeout for a script I want to run on the instance via the javascript client, however I do not see a way to set the executionTimeout. Specifically I've tried to put it in the parameters block as Parameters: { commands: [ ... ], "executionTimeout": "12000" }, (the type for command input requires that Parameters be { [key: string] : string[] }

Describe the solution you'd like

I'd like to have a way to specific the execution timeout that worked and documentation for it.

Describe alternatives you've considered

I'm considering abandoning this path and trying to manufacture AMIs. My enterprise-y setup makes all of this very challenging.
