Could not find username for email '${email}' in workspace. M

Error message

Could not find username for email '${email}' in workspace. Make sure the user exists in the workspace.

What it means

lookupUsernameByEmail built the workspace user cache via listUsers and found no user whose username or email matches the given email, so run-as identity resolution fails for settings like schedules/triggers that reference users by email.

Solutions

1. Confirm the user exists in that workspace (Users page or `wmill user list`).
