SendEmail failed. First exception on row 0; first error: INVALID_EMAIL_ADDRESS, Invalid to address : : [] Error is in expression '{!sendEmail}' in component in page MyPage: Class.MyClass.sendEmail: line 408, column 1

message.setOrgWideEmailAddressId(emailFromAddress);//emailFromAddress(string)-containing id
message.setCcAddresses(new String[]{emailCCAddress});//emailCCAddress(string)

message.setSubject(emailSubject);//emailSubject(string)
message.setHtmlBody(emailBody);  //emailBody(string)
message.setToAddresses(new String[]{emailToAddress.trim()}); //emailToAddress is a string containing '[email protected]'
//message.setToAddresses(new String[]{'[email protected]'}); //Tried this too still giving same error
Messaging.SendEmailResult[] mailResults = Messaging.sendEmail(new Messaging.SingleEmailMessage[]{message});// Line 408 where error occurs

Answer 1

Try validating cc and bcc addressess by checking null or empty

  if(emailCCAddress != null && emailCCAddress.trim() != ''){
        Ccaddress = emailCCAddress.split(',',0);
        mail.setCcAddresses(ccaddress);
        }
  if(emailBCCAddress != null && emailBCCAddress.trim() != ''){
        Bccaddress = emailBCCAddress.split(',',0);
        mail.setBccAddresses(Bccaddress);
        }

I would start by debugging this line, as it is likely causing the issue:

system.debug('EMAIL IS ' + new String[]{emailToAddress.trim()});

Then you can see if that is just not a valid email before you start to get crazy, most of the time it is something dumb that is holding you up, it is possible the value of 'emailToAddress' is not what you are expecting.
