When trying to retrieve historical workflow executions, is there any limit on how far back we can go? For example the generic code would look like

existing_execution = flyte_remote.fetch_execution(
            project=project, name=execution_name
        )
        return existing_execution

if it doesn't exist it will throw an error, however if it does but is ~1 year old, will there be any issues?

fetch_execution will only return one execution, are you talking about list execution?

I am aware, someone was just asking at work and I couldn't find docs on any kind of expiration date on historical executions. I am just trying to get a single one.
