AttributeError: 'CartoColorsMap' object has no attribute 'split'

my code is:
`from stylecloud import gen_stylecloud
gen_stylecloud(
    text=' '.join(list3),               
    size=512,                                
    font_path=r'‪C:\Windows\Fonts\msyh.ttc', 
    output_name='C:/Users/.../Desktop/wordcloud.png',
    icon_name='fab fa-twitter',  
    palette= cartocolors.qualitative.Bold_5  
)`
And this error occurred.
