Error while generating Vcard and attaching into mail.

Error while generating Vcard and attaching into mail.

  

I like to attach person details as Vcard into my mail. But often am getting this error(Refer Attachment).

Hi Vijya,

For us to help you, it's important to explain the steps you have already taken, apart from what you are trying to achieve. If I don't know in what way you tried to attach the vcard, I can't tell what's wrong with the way you are doing it.

Also, have you tried to debug your code? At what step the error appears? Do you call an Action or Function that has the mentioned "StartIndex" parameter? What is it's value?
