credentialdiggerScan cannot export findings

[david-lin-sap]

Hi team,
I use credentialdiggerScan step to scan secret in my repositories. I see some findings from log, but it didn't export csv file at last. Please help check the issue. Thanks.

My step config:
{"models":["PathModel","PasswordModel"],"exportAll":true,"repository":"<my_repo_url>"}
