Version

Please specify what version of the library you are using: [3.7.2]

If you are not using the latest release, please update and see if the issue is resolved before submitting an issue.

Expected / Desired Behavior / Question

Edit an item which has a lookup field, the lookup field source field is not Title, but another custom field. When open this DynamicForm to edit item, the exist lookup value disappeared.
This issue also occurred on MultiLookup field.
I suspect this is caused by that, the SPService.getLookupValue or SPService.getLookupValues has a hard code expanding the lookup field title field.

Observed Behavior

Lookup field value in DynamicForm is empty.

Steps to Reproduce

1. add a lookup field which source field is not Title tes list
2. add an item with the lookup field value filled
3. open this item with DynamicForm, the lookup field value is empty

Thanks!

@AJIXuMuK -I have do some test, but when the lookup field name is L1 or other 2 chars name, lookup value still cannot be display. In some case, items(ID) will return item data with odata field name based on sharepoint field internal name, but not internal name.

@yungfu - just to confirm - field name is 2 chars or field value?

[yungfu]

@AJIXuMuK 2 chars, lookup field name(not source field) is 2 chars, such as L1.

[AJIXuMuK]

@yungfu - could you please provide an example of your configuration?
I was trying to repro it and for me 2 chars field works correctly:

[yungfu]

@AJIXuMuK - dynamicForm is rendered in a webpat, only basic property setted.

let form = React.createElement(DynamicForm, {
      context: this.context,
      listId: '',
      listItemId: 257
    });

ReactDom.render(form, this.domElement);

List contains a lookup field named L1, L1 lookuped to an another list Text(also named Text) field not Title, this field value failed to display when loading.

If I delete this lookup field, and create another Text L1 field. Item resqust response L1 value following.

OData__x004c_1: "not lookup"

I have test this API in other test, if I chagne $expand=_x004c_1 to $expand=OData__x004c_1, expand lookup value successfully.

My SPO build version is: vti_buildversion:SR|16.0.22608.12005
