Issue/Introduction

SSPI UI crashes when expanding the certificate details under System -> Certificates -> VIEW CERTIFICATE CHAIN    after replacing the certificate 

 

Environment

SSP 5.0

Cause

The SSPI UI attempts to access `subject_alt_names.dns_names` when expanding the certificate details under System -> Certificates -> VIEW CERTIFICATE CHAIN.

If `subject_alt_names` is undefined, an error occurs: "Cannot read properties of undefined (reading 'dns_names')."

This indicates that the certificate used to replace the SSPI certificate was generated without Subject Alternative Name (SAN) details.

 

 

Resolution

Refreshing  the SSPI UI page will allow you to continue to log in to SSPI UI, or we  need to use the certificate that is generated with SAN details
