hello @aparnaalavilli, thanks for your question!!
an alternative to using the datepicker widget is to use individual inputs for the day/month/year and then convert over to a date without time using the PARSE_DATETIME_TZ() function.
for example, I have a text input for each of the elements:
which can then be parsed into a date:
resulting app:
the Formatted Date variable can then be used in the connector function. more information on the PARSE_DATETIME_TZ() function can be found here: Technical Details of the Expression Editor | Tulip Help Center - Support for Building Manufacturing Apps.
let us know if you have further questions!!
