I'm trying to generate a new self signed certificate, but don't seem able to in my production environment.  I can't find anything online as to why this might be.  Anyone have any suggestions? 

I'm using Simple Asset Manager by Salesforce Labs and one of the test classes is causing some problems when deploying new code.    

This is the error: 

Class NameMethod NameError MessageAM_HomeControllerTesttestRecordTypeSelectionSystem.AssertException: Assertion Failed: Expected: 0121R000001M5bAQAS, Actual: null

Am I reading that error correctly? Any help would be appreciated.  

I'm trying to generate a new self signed certificate, but don't seem able to in my production environment.  I can't find anything online as to why this might be.  Anyone have any suggestions? 

Hi All.
We received the following (see below) certificate expiration notice but when I look for this in our Certificate and Key Management section, within Setup, I am NOT able to find any such certificate with this Expiration Date.  Should I be looking elsewhere?  
Thank you for your time and advice.

"You have one or more certificates in your Salesforce org Navin, Haffty & Associates 00D2E000000no3I that will expire soon. Review the list below and visit Certificate and Key Management from Setup to make an update.

- SelfSignedCert_15Apr2019_184313, Self-Signed, expires on 4/15/2020. Warning: This certificate will expire in 30 day(s)."

I'm using Simple Asset Manager by Salesforce Labs and one of the test classes is causing some problems when deploying new code.
