[FIXED] MS graph api adding metadata to SharePoint file

Issue

I would like to add metadata to a SharePoint file. When i search the internet I find solutions like

graphClient.sites("{id}").drives("{id}").items("{id}").buildRequest().fields().patch(driveItem);

But I get the following message Cannot resolve method 'fields' in 'DriveItemRequest' When looking in the java doc, this method does not exitst.

An other solution is:

var fieldValueSet = new FieldValueSet();
fieldValueSet.additionalDataManager().put("Soort", new JsonPrimitive("Invoice"));
graphClient.sites("{id}").drives("{id}").items("{id}").buildRequest().patch(fieldValueSet );

But now I got the following message Required type: DriveItem, Provided: FieldValueSet

Sommething else i tried:

FieldValueSet fieldValueSet =  new FieldValueSet();
FieldValueSetRequest fieldValueSetRequest = graphClient.sites("{id}").lists("{id}").items({id}).fields().buildRequest();
fieldValueSet.additionalDataManager().put("Soort", new JsonPrimitive("new soort"));

return fieldValueSetRequest.patch(fieldValueSet);

Now I get a 400 back invalidRequest Error message: Invalid request PATCH

I also tried to extend DriveItem with my own property

CustomDriveItem customDriveItem =  new CustomDriveItem();
customDriveItem.soort = "new soort";
return graphClient.sites({id}).drives({id}).items({id}).buildRequest().patch(customDriveItem);

The extended class:

public class CustomDriveItem extends DriveItem {
    @SerializedName(value="soort")
    @Expose
    public String soort;

    public CustomDriveItem() {
        super();
    }
}

This also gives me a 400 back invalidRequest Error message: Invalid request PATCH

Solution

The driveItem object does not have fields - you'll need to transition to a listItem to access it. You could try:

var fieldValueSet = new FieldValueSet();
fieldValueSet.additionalDataManager().put("Soort", new JsonPrimitive("Invoice"));
graphClient.sites("{id}").drives("{id}").items("{id}").listItem().fields().buildRequest().patch(fieldValueSet );
