QJson not working in VS 2019 with Qt 5.15

[naubryGV]

When trying to visualize a QJsonDocument, or any QJson* object really, I'm not getting what I was expecting.
When empty:

When not empty:

please let me know if you want me to provide any more information.
I have tried to add the .natvis in either Program Files or My Documents VS folders but it wouldn't change a thing.

Here is what I'm getting when displaying Error and Warning of Natvis files:

Natvis: C:\dev\QJson.natvis(4,4): Warning: Unable to load a visualized preview for type 'QJsonDocument' because the conditions of all <DisplayString> elements were false.
Natvis: C:\dev\QJson.natvis(55,6): Error: Side effects are not supported in this context.
    Error while evaluating '((Qt5Cored.dll!QtCbor::ByteData*)(tt()->data.data() + (int)(tt()->elements.at(n).value)))' in the context of type 'Qt5Cored.dll!QCborContainerPrivate'.
Natvis: C:\dev\QJson.natvis(46,57): Error: class "QCborContainerPrivate" has no member "byteDataAt"
    Error while evaluating 'container->byteDataAt(n)->str(),[container->byteDataAt(n)->len]na' in the context of type 'Qt5Cored.dll!QCborValue'.

hope this helps

Thank you for using my natvis files. I assume you used the latest version of Qt. As I know, there are a lot of changes in Qt QJson. I don't use Qt products at the moment, so I can't help you, sorry.

More detail, though I do not know what it means:

Natvis: QJson.natvis(54,6): Error: Side effects are not supported in this context.
    Error while evaluating '((Qt5Cored.dll!QtCbor::ByteData*)(tt()->data.data() + (int)(tt()->elements.at(n).value)))'

@RichardTea do you have the .pdb files installed as well? Without them I think it's impossible for natvis to resolve the internals...

The nativs file provided by the visual studio qt plug-in works normally. QString can be visualized, but the added QJsonObject does not. Is this a problem with the pdb file?
