Thanks, we will handle this error. For your information, you have a SQL Task somewhere which is using a Credential that is not existing anymore. This causes the problem when the Task is being run. Do not have more information than that at the moment. I suggest you open all SQL Tasks one by one and then make sure a Credential is selected or "No Credential". Then save it by pressing OK. Do this on all.
