SharePoint REST API结果不包含查找字段

Question

I have a simple rest call on a lookup field:

_api/web/lists/getbytitle('Planning')/items(1)/?$select=Surveyor

however this returns 400, i know the field is definitely in the Planning list and it is a site column,

I do however, see SurveyorId, but i cant expand this.

Sorry for little information, thanks in advance.

Answer 1

does this field require expansion? if so make sure to try:

_api/web/lists/getbytitle('Planning')/items(1)/?$select=Surveyor/Title&$expand=Surveyor/Title
