I have created custom doctype named ‘contacts’ in custom module ‘meeting’ from there I want to make lead using custom button.
I have tried following code:

Hi @Pranali_Thorve,
You can’t use the decorator @frappe.whitelist() inside a class. Write that part of the code outside the class and also, there’s no need for indentation under the decorator.
