The error that you are facing is a typo. Please check your Custom configuration settings and make sure the paths to the certificates mentioned are correct.
java.nio.file.NoSuchFileException: C:\Users\userid\Documents\client certificate name
Additionally, you can also try removing the certificates in the Configuration tab as they are already imported in the certificates tab and see if it works or copy the path you have added in the settings and paste it in the Windows Explorer path to see if the file is actually present.
