i.e. in last element "Extension" in Json foramt all elements (like Search, Display and etc.) not have elements.
Please, help me solved this problem!)
I had a similar error, and solved it by only using the objects defined by the WSDL instead of using dicts.
I have the same issues ...
I do not understand why this library struggles with much of the WSDL ONVIF spec ???
