Can't convert string to date to set new date only field

I am trying to use an input from Power Apps to create a new record in a CDS entity. Below is part of my Flow configuration.


I am initializing a string variable called Modified with the value coming from Power Apps. While testing, it is 3/31/2020. In the compose, the full Expression is




The Create a new record is not shown in full but in the Date field, I am just selecting Outputs from dynamic content.

The error I get is "An error occurred while validating input parameters: Microsoft.OData.ODataException: Cannot convert the literal '03-31-2020' to the expected type 'Edm.Date'...."

The date field is Date Only type and in Advanced options, behavior is Date only

I am not sure what's wrong with this. I have tried a few other variations of date formatting but haven't gotten it to work. Are there any other problems I'm missing with this?



Have you tried using the convert time zone action?
In the action use Short date pattern as the format string.

Or try using
convertFromUtc('<Time to Format>', 'Pacific Standard Time', 'd')

You can swap the Pacific Standard Time with your time zone. But must follow Microsoft’s ISO

Thank you for the response. I tried using the Convert time zone which is working fine. I am using the Converted time output as my field in Create a new record. The conversion seems to work but am still getting the same error on Create a new record.


From Create a new record


In Create a new record, I also tried using the following expression

convertFromUtc('2020-04-01T08:00:00.0000000Z', 'Pacific Standard Time', 'd')

with both single and double quotes around d and got the same error 

"An error occurred while validating input parameters: Microsoft.OData.ODataException: Cannot convert the literal '04-01-2020' to the expected type 'Edm.Date'..."
