Queries the invocation result of a cloud assistant command, that is, the actual Output information of a specified ECS instance.

Description

After you use the DescribeInvocations interface to check the command invocation status and the returned InvokeStatus is Finished, it indicates that the command process is Finished, but not necessarily is as effective as expected. You need to check the Output parameter in DescribeInvocationResults to get the specific invocation result. The actual output result is the valid version.
