Hi,
Based on the logged exceptions, we know:
a. the scheduled report is attached to the World object.
b. the assigned password for the schedule creator's username was no longer valid.
So, you should be able to find the scheduled report under "World" --> "Reports"; and you should be able to delete it there.
To complete the "fix" for (b) i.e. you want to retain this scheduled report, you need to:
i. login as the user who owns the schedule.
ii. navigate to ANY scheduled report that this user owns.
iii. UPDATE the assigned password to the scheduled report. (Which updates the singular password stored for the user for all schedules.)
In other words, updating your password in the user management screens is not sufficient as it does not update the stored password for scheduled reports.
FYI, login credentials are usually encrypted into an irreversible form and stored. For scheduled reports and data collection, credentials are encrypted into a reversible form.
Hope this helps.
