[strongSwan] DH group for key exchange is undefined

I looked at the ike logs and I see the following message

[ENC] parsed IKE_SA_INIT response 0 [ N(INVAL_KE) ]
[IKE] peer didn't accept DH group MODP_1024, it requested MODP_1024

The packet capture shows the DH group is undefined. Is there a parameter to
set the DH group for the ike key exchange? I have the following parameter
in my load-tester.conf file.
proposal = aes-sha1-modp1024
