Exception in LogMessagesUC's LogGrid_CustomSummaryCalculate during/after Time Difference calculation

[Benedicht]

Describe the bug

I have an >50 Mb json file that i load with Json Log Parser. Right clicking and selecting Calculate time difference from this point throws a System.ArgumentNullException in LogMessagesUC.LogGrid_CustomSummaryCalculate at line 1138:

Analogy.LogViewer/Analogy.CommonControls/UserControls/LogMessagesUC.cs

Lines 1136 to 1139 in 3048699

	else if (e.SummaryProcess == CustomSummaryProcess.Calculate)
	{
	counts[(string)e.FieldValue] = counts[(string)e.FieldValue] + 1;
	}

Tried out both the pre-built v4.14.1 version and latest bits pulled down from the git repo. Both of them gave the very same result.

@Benedicht thanks for reporting. I'll check this

[Benedicht]

Thanks! Let me know if i can add any more details.

[LiorBanai]

I see you are using the json parser. Can you please add the mapped fields you are using so I can reproduce it faster

[Benedicht]

All json objects in the file should have both the date and level fields, no mapping should be needed.

ok thanks. I'll update :)

[Benedicht]

I have tested your commit and it's working correctly, thanks!
