This is the traceback of error

Traceback (most recent call last):

    values.name = doctype

The code I’m using is this:

      frappe.call({
      method: "frappe.core.doctype.communication.email.make",
      args: {
      recipients: "my_email@mail.com",
      content: b,                // this b variable contains html code
      subject: "Test",
      doctype: "Panel",          //name of doctype (is single doctype)
      name: cur_frm.doc.name,
      send_email: 1,
      communication_medium: "Email",
      },
      async: false,
      });

Any suggestion what I am doing wrong ?

This code is working when using in a normal doctype but giving the above mentioned error in is Single doctype.

If I comment the parameter name:cur_frm.doc.name, then mail is pushed to email queue but there, I’m getting this error:

Traceback (most recent call last):
  File "/home/frappe/frappe-bench/apps/frappe/frappe/app.py", line 61, in application

  File "/home/frappe/frappe-bench/apps/frappe/frappe/email/queue.py", line 483, in send_one
    raise e
AttributeError: 'NoneType' object has no attribute 'encode'

Any clue ??

EDIT
One more thing. If I am trying to send e-mail from here-> image
by clicking New Email, then also I’m getting this error:

name parameter is required for sending e-mail and here name is not getting but same name as of doctype name that’s why that error was coming. I guess if user selects is Single, New Email button shouldn’t be visible, just a thought :thinking:
