Error ASSERT: "!create" in file

  • Hello everyone,
    I created a function that fills an object and returns that object but after several calls to this function it gives me an ASSERT error: "! create" in file.
    I made debug and I know of the error in the return prop, it never goes into nullprt.
    Below i send image from code c++.

    Has anyone had problems filling out classes in c ++ and sending to qml like I am having.
    Thank you to all and have a nice day of programming .

    This can happen only if prop object is NULL. Looks like in some use case awi_base has NULL object somehow.

  • How can I pass the reference of an already filled object to the qml in a function?
    I already tried to return this object but the qml for some reason converts the object to "qqmlwatchproxy".
    Help-me, please
