I am getting error to verify my Paypal account

[c45a1e01]

I have only my First Name on all official documents. Upwork does not allow me to create an account without a last name.

Now when I enabled get paid option and linked my paypal account. It is showing that added PayPal account is inactive and not verified due to a mismatch of last name. My PayPal account has only my first name and last name with a (.) dot. 
Please help me.
