The Jenkins job that is scheduled to trigger every 15 minutes is consistently failing after midnight. During the day, when we're logged into Jenkins, the same job runs without any issues.

The failure appears to be caused by a script attempting to parse a JSON response from an API, which returns empty after midnight. As a result, the script throws a JSON decoding error because it expects a valid JSON payload.

This behavior suggests that the response from the API is either empty or malformed during that time window, likely due to the absence of a recent successful build reference.
