    I started getting this error today when opening some debug logs. 

    The actual exception seems to be this:

    WelkinSuite.Common.Extensions.NotParsedLogEventTypeException: Can not parse 'CODE_UNIT_STARTED' with 6 arguments. 
    	Log event parameters: '01qW00000004oII|CaseTrigger on Case trigger event BeforeUpdate|__sfdc_trigger/CaseTrigger'
    	Original message: 'Value does not fall within the expected range.'
    	at WelkinSuite.ApexLogParser.Implementation.LogEntryFactory.CreateLogEntry(String rawText, Int32 logLineNumber)
    	at WelkinSuite.ApexLogParser.Implementation.ApexLogParser.ParseLogEntry(String logEntryText, Int32 logLineNumber)
    	at WelkinSuite.EditorExtensions.ApexLogs.Classifier.ApexLogsClassifier.GetClassificationSpans(SnapshotSpan span)
    	at Microsoft.VisualStudio.Text.Classification.Implementation.ClassifierTagger.<GetTags>d__0.MoveNext()
    	at Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator`1.<GetTagsForBuffer>d__5.MoveNext()

    I'm guessing it is having a hard time with this line:

    09:13:30.713 (13082143341)|CODE_UNIT_STARTED|[EXTERNAL]|01qW00000004oII|CaseTrigger on Case trigger event BeforeUpdate|__sfdc_trigger/CaseTrigger


     This is making it difficult to do debugging. Is there anything I can do to prevent this exception? Maybe some edit I can make to the log file?

      Hi Dave,

      Thank you for sharing this with us.

      A reason for the issue is updated structure of log files on sandboxes which were moved to Summer'18 Salesforce version. According to changes in this SF version, some of the entries have another structure or another set of parameters.

      This is why the IDE cannot parse some entries properly.

      Our developers are working on this and we are going to include the necessary changes to the nearest version of TWS.

      This version will be available for you the nearest days.

      Best Regards,
