Apps Script MailApp throwing error : Exception: Invalid email: [L<?> (line 11, file "Code")

[Mallikarjunagowda Gowdara]

I am trying to send an email from app script by triggering a deployement. My code is as below:

function doGet(e) { 

   return SendMail(e); 

} 

function doPost(e) { 

  return SendMail(e); 

} 

function SendMail(e) { 

  var recipient = e.parameters.recipient; 

  var body = e.parameters.body; 

          MailApp.sendEmail({ 

              to: recipient, 

              subject: "Test Mail", 

              htmlBody: "Dear Sir/ Madam, <br> Test Code " +body+ , name: "Test App" 

  }); 

          return ContentService.createTextOutput(recipient) }

 

How ever its throwing an error : Exception: Invalid email: [L<?> (line 11, file "Code")

Kindly help me. I am properly passing the email Id. If I return the conterService,createTextOutput with recipient variable, it returns the proper email id.

Kindly help.

Please use:

var recipient = e.parameters.recipient.toString();

URL Parameters are passed as objects. This needs to be converted to string before calling sendEmail(). 

Also, in this line: htmlBody: "Dear Sir/ Madam, <br> Test Code " +body+ , name: "Test App" , I think the name is not defined anywhere. Is that a typo?

Also, the body variable also should be converted to string once you get it from the url parameter
