I have a set of 2 reports, their associated 2 report folders, 2 dashboards, associated 2 dashboard folders.
When I try to deploy via Change Set all of these 8 components, I get this error specifically for the 2 dashboards:
Cannot find a user that matches any of the following usernames: firstname.lastname@example.org, email@example.com; remove the user from the component being deployed or create a matching user in the destination organization.
I have no idea what is the issue.
I then tried to deploy the 6 components separately and it worked. So the issue seems to be with Dashboards.
I went into Dashboards and also set the Running User as "Run as specified user". Then I created a separate Change Set for these 2 dashboard items and tried to validate it in destination sandbox. Still the same error.
Can anyone please advise what is the issue and how can I resolve this?
