Action result object

Here's how action result object is structured (all keys are optional):

Name	When	Value
data?	Execution is successful.	What you returned in action's server code.
validationErrors?	Input data doesn't pass schema validation.	A partial Record of input schema keys as key or _root, and string[] as value. _root is a reserved key, used for global validation issues. Example: { _root: ["A global error"], email: ["Email is required."] }.
serverError?	An error occurs during action's server code execution.	A string that by default is "Something went wrong while executing the operation" for every server error that occurs, but this is configurable when instantiating a new client.
