Onboarding E-Signature Report With Empty Output

Summary

I have developed a job offer report that is sent to the successful candidate when they are moved to HR. The report is empty when displayed.

When the job offer report is processed under Tools > Reports and Analytics, it produces the expected output (Note that the query has hard-coded values, so should always produce the same output regardless of where it is executed).

See attached document for screenshots, as the output is not displayed when performed as a task of the onboarding checklist.

Has anyone experienced this, and can shed some light on resolution?
