In my SharePoint site, I have another subsite. On the top level site, there is a list to store 'document type'. Within the subsite, I have a document library which lookup the 'document type' list.
I need to get the lookup field values for the document library item which I query through REST API. The lookup field is 'Az_DocumentType'
Initially I got the document type id using the below sample:
However when I use the below code to get the value of the field using 'expand' I get the below error.
Error in Postman window:
The field 'Az_DocumentType' is not supported in the query. The lookup list is in another web.
Is there a way to get lookup field values as this in one go?
