shiboken6-genpyi with C++ class mapped to primitive type (dict)

Running shiboken6-genpyi against a Shiboken generated module wrapping a C++ library fails as follows:

The above exception was the direct cause of the following exception:

CuData has been mapped into a Python dict

<primitive-type name="CuData" target-lang-api-name="PyDict">
    <include file-name="cudata.h" location="global"/>
    <conversion-rule>
    <native-to-target file="glue/cumbia.cpp" snippet="return-cudata"/>
    <target-to-native>
    <add-conversion type="PyDict" check="PyDict_CheckExact(%in)" file="glue/cumbia.cpp" snippet="cudata-conversion-pydict"/>
    </target-to-native>
    </conversion-rule>
</primitive-type>

I don't know how to deal with this so that genpyi understands that CuData is python dict.

Thanks for any suggestion

OK. it seems that I found the modify-argument "pyi-type" is working.
With regards

Hi,

Glad you found out and thanks for sharing !

Would you mind posting the fixed version ? That might be useful to someone in the future.
