Running into a hard stop during our IaC pipeline for security compliance updates.
Environment:
- Terraform v1.6.4
- Genesys Cloud Provider v2.12.0
- Region: AU (Sydney)
- Target: genesyscloud_security_user
We are attempting to assign a new custom role to a batch of users via genesyscloud_security_user. The role exists and is active. The user accounts are active.
The apply fails with a 500 Internal Server Error from the Genesys Cloud API.
Error: PUT https://api.au.genesys.cloud/v2/users/12345678-90ab-cdef-1234-567890abcdef/security/roles returned 500 Internal Server Error
with module.security.genesyscloud_security_user.agent_role_assignment,
on security/roles.tf line 42, in resource "genesyscloud_security_user" "agent_role_assignment":
42: resource "genesyscloud_security_user" "agent_role_assignment" {
Debug logs show the request body is valid JSON. The role ID is correct.
If I do this manually via the Admin UI, it works instantly. If I use the REST API directly with Postman using the same token, it works.
It seems the Terraform provider is sending a malformed payload or missing a specific header that the API expects for bulk security updates.
Has anyone seen this specific 500 error with the genesyscloud_security_user resource in the last provider version? We need to push this compliance change out by EOD Sydney time.
Any workarounds or provider fixes? We are considering pinning back to v2.11.0 but would prefer to stay current.
The 500 Internal Server Error during genesyscloud_security_user assignment often stems from how the provider handles concurrent API calls when batch processing user roles. In my load testing environments, pushing role assignments for more than 50 users in a single Terraform apply frequently triggers rate limiting or backend timeout issues, especially in regions like AU where latency can add up.
The Genesys Cloud API has strict throughput limits for security-related endpoints. When Terraform attempts to parallelize these updates, it can overwhelm the local edge node’s capacity for that specific microservice. This is not necessarily a bug in the provider itself, but a capacity planning issue with how the requests are queued.
Try splitting the user assignments into smaller batches. Instead of one large genesyscloud_security_user block or a large loop, use a separate Terraform file or a for_each loop with a controlled concurrency setting in your backend configuration. If you are using a CI/CD pipeline, consider adding a delay or a retry policy with exponential backoff.
Here is a sample configuration to limit concurrency:
terraform {
backend "local" {
path = "terraform.tfstate"
}
}
# Limit parallelism in your CLI command
# terraform apply -parallelism=10
Also, verify that the custom role does not have conflicting permissions that might cause a validation error on the backend, which sometimes manifests as a generic 500 error instead of a 400. Check the Genesys Cloud audit logs for the specific timestamp of the failure. You might see a “rate limit exceeded” or “internal processing error” message that provides more context. If the issue persists, try applying the changes during off-peak hours to reduce the load on the platform.
