Release All

Cause credentialAlias value is wrong from 'discovery patter launch parameter' section(Serverless Execution Pattern - 'Pattern name').

Resolution Step 1: Go to Credentials table Step 2: Open Credential associated with the pattern and confirm its type is 'certificate management credential'. Step 3: Look on the 'Tag' value, eg. 'sn_disco_certmgmt.cert'. Step 4: Go to discovery schedules page and open the discovery certificate schedule Step 5: Discovery Schedule Page -> Related List -> Serverless Execution Pattern -> Open the record Step 6: Find the 'Discovery Pattern Launcher parameters' related list section. Find the 'credentialAlias' param and this value should be same as 'credential' tag display value from step 3.
