Presumably, CATS does not know how to work with ^x- custom extensions, could you please check this case?
Hi @vzhirnov. Is there a particular reason for using custom extension for these objects instead of just placing them in the Components section?
Hi @en-milie , sorry for long delay with the answer.
Yes, we can fix our swagger. And it will even be more conventional than using an extension for this, as we are currently doing. There are no good reasons for us to have just such a structure in the swagger. But your tool doesn't (sort of) follow the standard completely.
In short, we are not blocked by their bug, we can fix it ourselves. But you may want to fix this issue in your tool to meet the standard.
I understand. Currently CATS does not support custom extensions. We will think about how to best support this in future releases, but it might be tricky as these being "custom" it's hard to acomodate all possible behaviours.
