EasyRSA Error: The input file does not appear to be a certificate request. Aborting import. - OpenVPN setup on ubuntu

I’m currently following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-openvpn-server-on-ubuntu-18-04

I’ve successfully made it to the part where you transfer the client1.req cert request to the CA server but I am unable to import the certificate on the CA server. I get the following error: The input file does not appear to be a certificate request. Aborting import.

user1@server-CA:~/EasyRSA-v3.0.6$ ./easyrsa import-req /tmp/client1.req client1

Note: using Easy-RSA configuration from: ./vars

Using SSL: openssl OpenSSL 1.1.0g 2 Nov 2017

Easy-RSA error:

The input file does not appear to be a certificate request. Aborting import. Offending file: /tmp/client1.req

I don’t have a whole lot of experience with Linux in general so if more info is needed I will try to provide it. I’ve tried searching the web for hints but still haven’t been able to figure it out. Thanks in advance.
