return error on property changes

[Francine Sauvage]

Hi,
I cannot implement the following use case:

>From bmcweb code, I set RequestedPowerTransition.
>From requestedPowerTransition (phosphor-state-manager) code , I have a bad condition and I reject the transition.

==> How can I throw something (error code, exception ?) back to bmcweb in order to know what happened exactly ?

I was not able to add a "exceptions:" part in yaml around a property to create and throw a specific exception while getting / setting a property, like I did with methods.

I need to declare (and return) an exception while a property is changing, especially when the transition is not accepted.

I have an old version of openbmc, it may be solved in the new version, but please tell me how to help me eventually patching the needed parts,



Best regards,
Francine
