Version 18.3 breaks exporting grouped grid

Question

Exporting a grouped grid in version 18.3 to csv, excel or pdf all throw exceptions.

Here's sandbox example: https://codesandbox.io/s/syncfusion-grid-export-x2lcf?file=/src/components/Grid.vue

The last version that export works is 18.2.59.

Also captionTemplate in groupSettings doesn't work either even for display. I haven't created a sandbox example of that yet. But clearly 18.3 breaks some vital grid grouping features.

At a higher level, what sort of automated testing do you do to prevent these sort of regressions in new releases?

Thanks Ajith. I just noticed that if you remove the footerTemplate/groupFooterTemplate, then it works. So it seems the regression is related to that.
