BYOC Edge Connector 502 Bad Gateway during Terraform Apply

My configuration keeps failing…

Attempting to provision a new BYOC Edge instance via genesyscloud_edge_connector. The environment is set to au-2. Using provider version 1.56.0. The deployment pipeline runs via GitHub Actions on ubuntu-latest. The Terraform apply fails consistently at the genesyscloud_edge_connector resource creation step. The error log indicates an HTTP 502 Bad Gateway returned from the Genesys Cloud API endpoint /api/v2/edge/connectors.

The payload sent includes standard configuration: name, description, region set to ap-southeast-2, and capacity set to 10. No custom certificates or advanced routing rules are attached at this stage. The issue persists across multiple runs. Rolling back to provider 1.55.0 did not resolve the connectivity issue. Direct API calls using Postman with the same OAuth token succeed, suggesting the issue is specific to the Terraform provider’s request handling or timing. The error message is generic: Error creating edge connector: 502 Bad Gateway. No detailed JSON error body is returned, making debugging difficult. The environment variables for GENESYCLOUD_CLIENT_ID and GENESYCLOUD_CLIENT_SECRET are verified correct. Network connectivity to api.au-2.genesys.cloud is open. Firewall logs show no blocked requests. Suspect a transient issue with the Edge provisioning service in au-2 or a bug in the provider’s retry logic for this specific resource type. Need to know if others face this 502 error with BYOC resources in the Sydney region. Is there a known workaround or a specific header required in the Terraform provider configuration that is currently missing? The standard documentation does not list any additional requirements for basic connector creation.

The easiest fix here is this is to bypass the standard genesyscloud_edge_connector resource creation entirely for the initial registration phase and instead leverage the Genesys Cloud REST API directly via a null_resource and local-exec provisioner, as the Terraform provider often struggles with the asynchronous nature of SBC provisioning in the APAC region due to strict timeout limits on the API gateway. When managing 15 BYOC trunks across multiple regions, specifically in au-2, the edge connector registration involves complex SIP credential generation and certificate validation that the provider version 1.56.0 does not handle robustly, leading to the 502 Bad Gateway error when the underlying service is still initializing the virtual SBC. Instead of waiting for the provider to retry, which usually fails, execute a direct POST request to /api/v2/telephony/sbc/edge-connectors using your admin API key to force the immediate creation of the edge instance. Once the API returns a 201 Created status and provides the edgeId, you can then use that ID to import the resource into Terraform state using terraform import genesyscloud_edge_connector.my_edge <edgeId>. This approach ensures that the SBC is fully registered and active before Terraform attempts to manage its configuration, avoiding the race condition that causes the 502 error. Additionally, ensure your outbound routing policies are not blocking the IP ranges used by the APAC edge nodes, as misconfigured firewall rules can also manifest as gateway errors during the initial handshake. Always verify the SIP registration status via the Admin console before proceeding with further automation steps to prevent cascading failures in your CI/CD pipeline.
