Dateflows issues with Dates

We have created a Dataflow that connects to on-prem sql-server trough a gateway. The purpose is to store the date in Dataverse for further use.


Error message in Dataflow


{"error":{"code":"0x0","message":"An error occurred while validating input parameters: Microsoft.OData.ODataException: Cannot convert the literal '2020-02-10T00:00:00+00:00' to the expected type 'Edm.Date'. ---> System.FormatException: String '2020-02-10T00:00:00+00:00' was not recognized as a valid Edm.Date.


Part of the detailed error:{
    "cr8f7_chdt": "2020-02-10T00:00:00+00:00",



The field/column in Dataverse is created as Date Only. We expect the format to be : yyyy-MM-dd


Using the web api in Chrome, we get the following output, as expected:


  "@odata.context": "$metadata#cr8f7_xxxx/$entity",
  "@odata.etag": "W/\"51229613\"",
  "cr8f7_chdt": "2020-02-10",



Question is, how can we work around this issue?

Hi @joh,


For the Dataverse column, is the behaviour set to Date Only as well? If so, you should add a transform in your dataflow to send only the Date part (YYYY-mm-dd). 


If it's set to User Local, then try tweaking the format.  E.g. 2020-02-10T00:00:00.000Z

Hi @ChrisPiasecki  and thanks for your reply!


What we have done is to convert the date field we get from the SQL-server to "yyyy-MM-dd" as text in PowerQuery. Then we use that field to load to Dataverse as date, this works.


The error happens when an upsert/compare is done and Dataverses reads the data as the long format causing the error. We moved to store it as text for now to avoid the date issue.
