When I go to Monitoring -> mta@<my_instance> -> Open Journal log
i got below error:
SOP-330011 Error while executing the method 'GetLogFileList' of service 'nl:monitoring'.
It looks like a permission issue, i checked the nl:monitoring schema and find out that method 'GetLogFileList' does have a acceee='admin' and hidden='true'.
but my login account are in the admin permission group.
this confuses me why it still throw this error when i tried to open the journal log.
this error is related to your access to the log file.
Could you, please, temporary add all other permission groups to the your user, perform hard cache delete (https://helpx.adobe.com/campaign/kb/how-to-perform-soft-and-hard-cache-clear-when-the-issues-are-mac...) and try again?
it seems someone got the same error and cleared it with the below steps.
