When altering a SharePoint list form with Power Apps, I receive this error when trying to add to the list using the Power Apps form: "Network error when using Patch function": The requested operation is invalid."

Hi @Jeannette Gilpin,

As far as I know, there are many situations when this exception occurs:

1. You modified the data type, but did not refresh the data source, causing the submission to fail.
2. There are required columns in your list, but you do not have a patch.

Can you provide your patch formula and the properties of the relevant columns (such as choice columns or text columns)?

If you want to catch the problem through exception catching, try

Hi @Jeannette Gilpin

Did you create a column with unique values?

If there are duplicates in this column in the records you submit, the above error will also appear!
