We have a query that is executed by an “experience site/community” user. The user has “Partner Community” license and “Partner Community User” profile. This user executes code containing the following query and gets “System.QueryException: Insufficient permissions: secure query included inaccessible field” error.
SELECT contentdocumentid, linkedentityid, contentdocument.description, contentdocument.fileextension, contentdocument.filetype, contentdocument.ownerid, contentdocument.contentsize, contentdocument.title FROM ContentDocumentLink WHERE LinkedEntityId IN :objectIds WITH SECURITY_ENFORCED
The “WITH SECURITY_ENFORCED” clause is supposed to check object and field level security. Since the object and field level security is not exposed for ContentDocument or ContentDocumentLink, I am thinking that there is some other setting which automatically enables the object and field level security.
If you know what that setting is, please let me know. If I can’t find the setting I am inclined to remove the “WITH SECURITY_ENFORCED” clause from the SOQL query and try.
So it looks like your issue is that you're trying to access fields on related objects, which is not something you can do when you specify
WITH SECURITY_ENFORCED. From the documentation:
