Unable to update API target URL after upgrading from tyk 2.3.8 to 2.5

I am using Tyk on-premise setup on Ubuntu 14.04.
Few days ago I updated Tyk-dashboard (from v1.3.6 to v1.5.1) and gateway (from 2.3.8 to 2.5.1).
I am using same configuration files which I was using for older version, things are looking fine but I am unable to update target URL for API. It’s showing following error.

API object validation failed.
upstream_certificates: Additional property upstream_certificates is not allowed
tag_headers: Additional property tag_headers is not allowed
client_certificates: Additional property client_certificates is not allowed
global_rate_limit: Additional property global_rate_limit is not allowed
use_mutual_tls_auth: Additional property use_mutual_tls_auth is not allowed
strip_auth_data: Additional property strip_auth_data is not allowed

Am I missing something ?

Any help on this will be highly appreciated.
Thanks :slight_smile:

I don’t know reason for this error. Installed same version on other system and worked there, so I reinstalled on the system where I was getting error now It’s working fine.
