Beneficiary Name misspelled in I129 petition

[Yogeesh]

Can someone help me to know if I can appear for H1b Stamping if Beneficiary name misspelled in petition. 

Actual Name: ABC XYZ QWE 
Name appears in petition ABC XZ (in middle name 'Y' and last name QWE is missed in petition copy) 

1. Can I go for stamping with this misspelled petition copy. 
2. Do I need to correct this name from USCIS (it was a cap exempt case and initiated in premium process). 
(As per old petition Beneficiary name was correct) 

Thanks in advance

Better to get it corrected to be safe if you can.
