Documents for Naturalization as the spouse of Us citizen

[eddin2020]

I applied for Naturalization on October 2019 as spouse of Us citizen. I have been married for 4 years now.
My wife was Naturalized when she was a child with her family, so she never received a naturalization certificate or a certificate of citizenship .
Today I revived my interview appointment but they are asking for birth-certificate ( my wife was not born in the us) or naturalization certificate or a certificate of citizenship.
We only have her Advanced Drivers-licence ( Washington state) with her new last name or an active passport with her maiden name.
I am not sure what to do. My interview is in 3 weeks and it takes 9 month to get certificate of citizenship.
Did anyone had this issue before? What should I do?
