The reason you get this error comes down to the fact that you added the Create button on the toolbar.
When a data source section is added to the grid, it looks for the path to the create command.
eg. for your reading action you have
.Read(read => read.Action("LoadAllkazangAccounts", "Kazang"))
so you need to add the corresponding insert action, for example:
.Create(create=> create.Action("CreatekazangAccounts", "Kazang"))
if you donβt need to create anything in this grid, then simply remove the create toolbar menu item from the grid.
