Posted on by Ahmad Ali

Creating an app for a school in which there is a screen which adds students to a sharepoint list. The list has two columns: Title and Class, Title being the name of the student. My code didn't give any errors however when i tried to make an entry it did "Students failed: Object must implement IConvertible.
clientRequestId: 497f83b6-5149-4ae1-8346-07a10544d656
serviceRequestId: aecefda1-20f9-f000-d0ef-6c5c255492a7". The code i used is the following:

If(
    IsBlank(txtStudentName) || IsBlank(cmbStudentClass.Selected),
    Notify("❌ Please enter student name and select a class.", NotificationType.Error),
    Patch(
        Students,
        Defaults(Students),
        {
            Title: txtStudentName,
            Class: {
                '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
                Id: cmbStudentClass.Selected.ID,
                Value: cmbStudentClass.Selected.Title
            }
        }
    );
    Notify("✅ Student added successfully!", NotificationType.Success);
    Reset(txtStudentName);
    Reset(cmbStudentClass)
)

Hello,

try this:

If( IsBlank(txtStudentName.Text) || IsBlank(cmbStudentClass.Selected), Notify("❌ Please enter student name and select a class.", NotificationType.Error), Patch( Students, Defaults(Students), { Title: txtStudentName.Text, Class: { '@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference", Id: cmbStudentClass.Selected.ID, Value: cmbStudentClass.Selected.Title } } ); Notify("✅ Student added successfully!", NotificationType.Success); Reset(txtStudentName); Reset(cmbStudentClass) )

You are passing the entire textinput control to SharePoint which is why its complaining. You need to specify the value/text =)

Thank you Fredrik. I thought the problem was with the class problem and was focusing on it. I later understood that it was the text field making the error. Your solution is correct.
