Unable to write to a Table on Azure SQL Data Warehouse from Microsoft PowerApps



I have created a SQL Server connection to an Azure SQL Data Warehouse instance, and able to view all the data from the selected tables in my Power App. I can also add an 'Edit Form' to this data source, on to one of my screens. However on the SubmitForm() function, it throws an error - "An error occurred on the Server. Not a valid connector". I looked for official documentation, whether this is a limitation by design, and found none. Kindly help me with appropriate information on the same.


Attached screenshot of the error message on my PowerApp function.

Hi Abhijith,


Looking through your issue here typically errors like this occur when either the data format you are sending via is incorrect or if the server you are sending to wasn't expecting any data. Looking at your logic here I am not sure where the error is occurring, the logic appears to be correct to me. For this issue you might want to open a case with Microsoft Support, I'll include a link below if you would like to go down that route. Otherwise if any other communities member might know what the issue is feel free to pitch in.


If you would like to create a ticket with Microsoft Customer Support here is a link on how to do so:
