Symptom
A connector job fails with an HTTP 403 Forbidden error when attempting to upload data to the platform.
Cause
Connectors authenticate using a client certificate. The platform associates that certificate with a user identity, and access to platform objects is controlled by the roles assigned to that identity. A 403 error means the user identity linked to the connector's certificate does not have permission to access the object used to receive the uploaded data.
Resolution
Open the connector's About screen and note the Certificate Distinguished Name. This is the identity the platform uses for this connector.
In the platform, locate the user account associated with that distinguished name.
Review the roles assigned to that user and confirm they include access to the object used for data ingestion.
If the required permissions are missing, update the user's role or resource access accordingly.
Once the correct permissions are in place, re-run the connector job. See Configuring OData Resources for guidance on resource and role configuration.
