Invalid bundle: mandatory fault rule name

[#1]

Hi,

I am able to upload the new revision to apigee (using apigeetool), but whenever I change anything (even add a spacebar) in code and try to save it, the following error appears:

Error Saving Revision 123
Bundle is invalid. Errors:[Entity : Target, Fault rule name is mandatory;Entity : Proxy, Fault rule name is mandatory;].

Does anyone know what might be causing that? I have checked the fault rules and they all seem to be fine, and deployed config works properly. The only problem is with saving any changes.

It turned out that "name" attributes of FaultRule elements are mandatory, but it's not enforced when uploading using apigeetool. Problem solved.
