"Uncaught TypeError: Cannot read property 'time_point' of null" Error in Mask Tool

[dwh1121]

Hello author,

Thank you for providing such a useful tool for everyone to use.

When I use the Mask Tool to draw the mask, and press the Done button. I cannot add polygon. I can find the "Uncaught TypeError: Cannot read property 'time_point' of null" error message in the Console.

I can correct this error by modifying the following code:

LabelMeAnnotationTool/annotationTools/js/handler.js

Lines 313 to 314 in 0e8b9f5

	html_str += '<timefirst>' + draw_anno.time_point[0] + '</timefirst>';
	html_str += '<timesecond>' + draw_anno.time_point[1] + '</timesecond>';

To:
html_str += '<timefirst>' + anno.time_point[0] + '</timefirst>';
html_str += '<timesecond>' + anno.time_point[1] + '</timesecond>';

Hope this finding can help everyone.
