Requirement :

We look into, where the columns in SharePoint are in Single-line-of-text and where the fields in Power App screen are Date picker
So we need to ‘sort’ the data by the date column in the PowerApp and save the Date values into the Single-line-of text

Get the required datacard (single line of text) into the application ,

> Here the datacard named as Date.

>Delete the default datacardvalue in datacard

>Insert a datepicker into datacard of Date

>Post Inserting the datepicker

>Delete the Default Datacardvalue comes with the datacard

> Update the datepickervalue name into the error occurred

> After updating the datepicker value into the items & update properties , you will see no errors

So, now you enter the details and click on submit button the items gets stored into the share point list ,

>Then the item get stored into the column ‘Date’ which is in single line of text but the datacard in the app is in datepicker format.
