NPE from scheduleFeedbackSessionPublishedEmail #10974

damithc · 2021-02-21T04:24:44Z

This error happened soon after both times I deployed v7.10.0 (I rolled back both times). First time I wasn't sure if the error is caused by a change in the new version. After the second time, seems too much of a coincidence.

v7.10.0

Let us know if this issue is not resolved with #10930 (comment)

damithc · 2021-02-23T04:46:33Z

After setting the region in build.properties, I did not receive any errors. Unfortunately, it's because even the error reporting mechanism (which relies on the task queue) stopped working. Only realized the problem when a few users reported not being able to send reminders to students. I rolled back to the previous version after that.

There are several errors in the log, but all mention permission issues.

Solved by giving 'Editor' permissions to the gserviceaccount

Thanks @wkurniawan07 for the solution info

The 'log compilation' cron job that runs every 5 minutes still seems to have some problem.

That is a known issue (googleapis/google-cloud-java#3693) and is not a cause of concern (at best, just some annoyance). It does not affect the logs being fetched. Can think of it as something like resource failed to be closed.

I see. Well, this means I'm going to receive an error log email every 5 minutes. I can't simply ignore them either, as the email can contain other error messages. So, looks like we'll have to find a way around it? Perhaps we can update the log compilation task to ignore this specific error? googleapis/google-cloud-java#3693 says it is fixed and to be released but that was more than 1 year ago.

teammates/src/main/java/teammates/ui/webapi/CompileLogsAction.java

Lines 61 to 69 in 4e44320

    
           Page<LogEntry> entries = logging.listLogEntries( 
        
                   EntryListOption.filter(logOptions.stream().collect(Collectors.joining("\n"))) 
        
           );

           } 
        
           return logs;

@damithc can try adding this before the for block above:

        try {
            logging.close();
        } catch (Exception e) {
            // ignore exception when closing resource
        }
