Date not passing correctly from app to flow

I've built an app with a datepicker that sends info, including this date, to a flow that places it in a sharepoint list. The following error is happening:


The request from the app shows:



The app is expecting to send out a date: 


The flow is set up to send this to a column in the sharepoint list that is formatted for date-only.

Can anyone tell me why this error is happening and what else I need to do to make this date readable for the flow? TIA.

Hi @BCLS776 :

I'v made a similar test but did no encounted the problem you mentioned.

I suggest you convert the text type parameter ‘triggerBody()?[’Createitem_WorkDate’]’ into a date type in flow and try again.

For example:

Hi @v-bofeng-msft ,

I tried the solution with the formatDateTime expression in the flow and the same error continues to come up.
I also tried:
- Disconnecting the flow from the app and re-establishing the connection with a new Run function call

- Replacing the datepicker argument to the Run function call with a Today()


The result is the same in all cases: a run-time error for the app attempting to pass a string into a date column. Any other ideas?
