Likely Causes
  1. Caller identity is valid but lacks authorization for the targeted resource/action.
  2. Role/scope mapping in workspace or account policy does not include required privilege.
  3. Resource-level ACL or tenant boundary prevents this operation for current principal.
How to Fix It
1
Twilio: Verify the exact permission/scope required by the endpoint and compare with granted scopes.
2
Check workspace/team/project role bindings for the acting user or app integration.
3
Confirm the target resource belongs to the same tenant/account context as the token.
4
Apply least-privilege scope updates and retry with explicit authorization checks.
5
Log permission-denied events with resource identifiers for faster future triage.
