Not able to access ContentDocumentLink on Site VF page's Controller(without sharing)

Question

SOQL:

[SELECT ContentDocumentId FROM ContentDocumentLink WHERE LinkedEntityId = {{reocrdID}}]

OR

SELECT Id, (SELECT ContentDocumentId FROM ContentDocumentLinks) FROM {{sObjectAPIName}} Where id = {{recordID}}

On Anonymous window: returns list of files attached with particular record

On Internal VF page controller (without sharing): returns list of files attached with particular record

On Site VF page controller (without sharing): returns empty list

Is there any configuration/access permission needs to be granted for site guest user?

Answer 1

I think that queries directly on Content are picky and don't always display everything other users own, even if it's visible to the user by permissions or by way of without sharing.

Perhaps you can try querying the record instead, and subquerying its ContentDocumentLinks list?
