After update from 7.9 to 8.0.16 I have the error below in my main project :
ERROR(500): Error executing function 'RunQuery': The current user does not have the required roles for this operation.
Client permission denied for user admin: key=legacy-db
So my client tag can't run an SQL query.
Can you help me ? Is there any configuration to do in gateway ?
Phil’s answer is correct, but I find the error a bit odd - this should only be an issue for new projects since Ignition 7.9.4. Existing projects from before 7.9.4 should have legacy database access by default.
