Hi @SameerShahzad99 - Thanks for posting the issue. I can reproduce the issue.

However check these points as well. For choice chips widget, allow multi select is enabled? if this option is on, you can't map the selected values to a string as value type is list. And also check that you have provided a default value while binding selected value to a text widget.

Hi @hariprasadms, Thank you so much for looking into this issue, the problem is that i am unable to assign a list of strings values here as well.
