Is there a clean way to configure the genesyscloud_byoc_edge resource when using Terraform provider v1.9.2? The deployment pipeline in GitHub Actions fails during the terraform apply stage. The environment is au-1. The edge is registered, but the configuration update returns an error.
400 Bad Request: Invalid configuration schema for BYOC edge node
The HCL definition is standard. The config block contains the required hostname and port fields. The JSON payload sent to the API matches the schema documented in the BYOC guide.
hcl
resource "genesyscloud_byoc_edge" "main" {
name = "prod-edge-au-1"
description = "Production BYOC Edge for Sydney"
config = jsonencode({
hostname = "edge.prod.example.com"
port = 443
protocol = "https"
})
depends_on = [genesyscloud_byoc_edge_registration.main]
}
The genesyscloud_byoc_edge_registration resource completes successfully. The edge status shows as ONLINE in the UI. However, when Terraform attempts to push the configuration, the API rejects it. The debug logs from the CLI show the request payload is valid JSON. The response body indicates a field validation error, but no specific field is named.
Running the same configuration manually via the REST API endpoint /api/v2/builder/byoc/edges/{edgeId}/config works without issue. The issue appears isolated to the Terraform provider or the CLI wrapper used in the pipeline. The provider version is up to date. The CLI version is v2.4.0.
Is there a known issue with the config block handling in recent provider versions? Or is there a specific format required for the JSON encoding that differs from standard JSON? The error log does not provide enough detail to pinpoint the invalid field. The timezone is Australia/Sydney, so UTC offsets are consistent. No drift detected in state file. The problem persists across three consecutive runs. Seeking insights on how to debug the exact field causing the 400 error or if there is a workaround for this provider limitation.
It depends, but generally… the BYOC config schema in v1.9.2 is stricter than previous versions. Try wrapping your custom settings in a metadata block within the Terraform resource.
This usually bypasses the initial validation error. The platform API expects specific nesting for custom attributes during the handshake. Check the JMeter logs if it still fails.
As far as I remember, the strict schema validation in v1.9.2 is a common hurdle when migrating from Zendesk’s more flexible ticket field structures to Genesys Cloud’s rigid BYOC Edge configurations. The suggestion above about using the metadata block is spot on, but there is an additional layer of complexity regarding how custom attributes are nested. In Zendesk, we often just dumped custom data into JSON objects, but Genesys Cloud requires a specific hierarchy for the handshake to succeed. You need to ensure your custom settings are not just in metadata, but also properly referenced in the config block’s attributes map. Here is a working snippet from a recent migration project in the eu-1 region that might help clarify the structure:
resource "genesyscloud_byoc_edge" "my_edge" {
name = "Production-Edge"
description = "Migrated from Zendesk Digital Channels"
config {
# Standard required fields first
max_concurrent_sessions = 500
timeout_seconds = 30
# Custom attributes must be explicitly mapped
attributes = {
"zendesk_ticket_id" = "${var.zendesk_id}"
"priority_tag" = "${var.priority}"
}
}
}
The key difference is that Genesys Cloud validates the attributes map against a predefined schema during the initial registration, whereas Zendesk allowed arbitrary key-value pairs. If you omit the explicit attribute mapping, the API throws that 400 Bad Request error because it cannot reconcile the custom data with the expected interaction model. Also, check your Terraform provider version compatibility with the au-1 environment, as regional endpoints sometimes have slight schema variations. This structure worked for us when moving digital channel workflows over, ensuring that private notes and custom fields were preserved without data loss.
How I usually solve this is by ensuring the config block strictly adheres to the v1.9.2 schema. The metadata wrapper mentioned earlier is correct, but verify the sip_profile_id matches the BYOC trunk registration exactly. In APAC regions, a mismatch here causes the 400 error during the handshake phase.
