Anyone know why the GC provider v1.68.4 returns a 403 Forbidden when applying SIP trunk configurations in AU-1 BYOC? The genesyscloud_sip_trunk resource fails with Error: PUT /api/v2/telephony/sip/sites/trunks/... 403 Forbidden. The payload validates fine via Postman. Using standard OIDC service account. Terraform state is clean.
