@likhitha_j Thank you. I have already done this as it was similar to the solution @chandra_sekhar provided in my post [To build Mock MDS - Step 3 error - how to resolve? - #3 by chandra\_sekhar](https://community.mosip.io/t/to-build-mock-mds-step-3-error-how-to-resolve/569/3) I encountered the same error in that post even after doing all the steps. Anyway, it looks like the locally built partner management tool 1.2.0 is incompatible with the other dependencies/modules running in our MOSIP platform. As of now, I have already managed to create _ **artnerApiKey** _ and _ **partnerMispLicenseKey** _ using Swagger UI - running on our MOSIP K8s cluster and CA\_CERT\_UTILITY. The remaining issue for me is which of the Device.p12 should I use and rename so that i could build the Auth demo UI as I have asked above. auth-ca.p12 - is this from AUTH partner ? do I just rename Device.p12 created through CA\_CERT\_UTILITY ? auth-inter.p12 - is this from MISP partner ? do I also just rename Device.p12 created through CA\_CERT\_UTILITY ? auth-partner.p12 - also from MISP partner ? do I just rename Device.p12 created through CA\_CERT\_UTILITY ? --- _[View the full topic](https://community.mosip.io/t/auth-demo-ui-certificate-exchange-with-partners-error-when-using-localhost-swagger-ui/691)._
