The Base64Binary type doesn't accept collections as value

ZEEP 4.1.0 Python 3.9.7

Hi, Thanks in advance for the support. I have a problem with invoking a service that has a base64 element as its element. The "stream" parameter is a base64 and building the object from ZEEP I get an error of the type reported in the object. WSDL online

` message = "Python is fun" message_bytes = message.encode('utf-8') base64_bytes = base64.b64encode(message_bytes)

identity_val={'delegated_domain': 'demoprod', 'delegated_password': 'password11','stream':base64_bytes,'delegated_user':'delegato' ,'otpPwd':'dsign','typeOtpAuth':'demoprod','user':'titolare_aut'} parameter_val={'type':'XMLENVELOPED'} parameter = parameter_type(parameter_val) signRequestV2_val={'certID': 'AS0','requiredmark':'true','identity':identity_val,'transport':'STREAM'} signRequestV2 = signRequestV2_type(signRequestV2_val)`

Error: raise ValueError( ValueError: The Base64Binary type doesn't accept collections as value

I also tried to pass the parameter directly to the method instead of putting it in the Collection but the result is the same.

Thanks for support
