Why am I getting a "The specified column is generated by the server and can't be specified" error?

[Mgodby]

I have a SharePoint list that I am writing to in my PowerApp. Everything works fine except for the Image column of the list. The text fields all work fine but this one image field is giving me errors on PowerApps.

When I try to do a patch on the image column "Seat Picture" I get an error saying "The specified column is generated by the server and can't be specified".

I've heard that that means that the column doesn't exist but it does.

Is this just a limitation for image fields/columns?

Hi @Mgodby ,

Sorry if this is a silly question, but your SharePoint text field is a Multi Line Text item?

Hi @Mgodby ,

Is the image column that you mentioned data type picture?

If so, this data type is read-only in powerapps.

I'm afraid it' not supported to update picture data type by using powerapps.

You could only display the data of picture field in powerapps.

If you want to update picture field, you could only update it in sharepoint.

As an alternative way, I suggest you try to use hyperlink field.

This data type could be updated in powerapps.

Here's a doc about sharepoint in powerapps for your reference:

Please notice the Known issues part.
