Sharepoint connector - Hallucinating Deep Research

Deep Research can’t find our onedrive data and hallucinates non-existent files. What are we missing?

Consent wise (via MS Entra):

  • Users ‘assigned’ under “Enterprise Apps” in Entra.
  • “Grant Admin Consent for ..Tenant…” → Activated.
  • Permissions and delegated consents (files.read.all, offline_access,sites.read.all,user.read) are activated for the MS Graph API (both admin consent and user consent).

Separate checks using MS Graph Explorer with same consents are giving correct expected responses.

Any help appreciated.

anyone else having this issue?
