[cpp-pistache-server] newItem.fromJson() always called even when type is std::string #1251
Description
Description
The fromJson method defined via model-source.mustache declares newItem to be of type items.datatype. When processing an array of stings this results in generating declaring newItem as std::string and subsequently attempting to execute the fromJson() method which is undefined. In this case, here is a snippet of the generated code for UePerLocationReport::fromJson(nlohmann:json& val).
...
void UePerLocationReport::fromJson(nlohmann::json& val)
{
setUeCount(val.at("ueCount"));
{
m_ExternalIds.clear();
nlohmann::json jsonArray;
if(val.find("externalIds") != val.end())
{
for( auto& item : val["externalIds"] )
{
if(item.is_null())
{
m_ExternalIds.push_back( std::string() );
}
else
{
std::string newItem;
newItem.fromJson(item);
m_ExternalIds.push_back( newItem );
}
}
}
}
