I have error C2556 with message

juce::AudioProcessor \*juce::createPluginFilterOfType(juce::AudioProcessor::WrapperType)’ : la fonction surchargée ne diffère que par le type de retour de ‘std::unique\_ptr\<juce::AudioProcessor,std::default\_deletejuce::AudioProcessor\> juce::createPluginFilterOfType(juce::AudioProcessor::WrapperType)’|ArpeggiatorPlugin\_SharedCode|D:\Program Files\JUCE\modules\juce\_audio\_plugin\_client\utility\juce\_CreatePluginFilter.h|38

Do you have idea for resolving this message ?
