Could use a hand troubleshooting this validation failure when migrating complex routing logic from Zendesk Triggers to Genesys Cloud Architect. We are currently porting a high-volume support queue that relied heavily on Zendesk’s tag-based conditional branching. In the new GC environment, we are attempting to replicate this using the If statement block within the Flow Canvas.
The specific issue occurs when we try to save a flow that checks for multiple custom attributes simultaneously. Instead of a clean save, we get Error 422: Unprocessable Entity - Validation failed for node 'Condition_Check_Tags'.
The JSON payload shows the logic is syntactically correct, but the validation engine seems to choke on the nested AND conditions referencing attributes that were recently imported via the bulk API. In Zendesk, these tag checks were instantaneous and required no pre-validation. Here in GC, it feels like the system is waiting for attribute schema propagation.
Has anyone dealt with this latency during migration? Are we missing a step in the attribute definition phase before the flow can reference them? The documentation suggests attributes must be ‘active,’ but we verified that in the Admin console.
It depends, but generally… this validation error stems from schema mismatches or invalid node references during high-volume flow updates. The documentation states the version field must match the retrieved flow exactly. If the version drifts, a 400 error triggers immediately. Also check for duplicate id values in the payload.
To fix this in a load testing context:
- Retrieve the current flow version via
GET /api/v2/flows before any update.
- Ensure the
version field in your JSON payload matches the retrieved value exactly.
- Verify all
node_id references exist in the canvas before saving.
- Use JMeter to validate the API throughput limits. Send small batches first.
We saw similar issues when pushing 100 concurrent messaging sessions. The 429 Too Many Requests error appeared because we hit rate limits. Check your API rate limits. If you are migrating from Zendesk triggers, map each tag to a specific custom attribute in GC. Do not try to replicate complex branching logic in one go. Break it down into smaller flows. This helps avoid timeout errors during validation.
Have you tried validating the flow JSON against the schema before applying via Terraform?
resource "genesyscloud_flow" "zendesk_migration" {
# Ensure custom attributes are defined in the 'custom_attributes' block
custom_attributes = {
"zendesk_tag" = {
type = "String"
}
}
}
The validation error usually hits when the attribute isn’t pre-defined in the flow config.
It depends, but generally… schema validation fails because custom attributes must be explicitly defined in the flow metadata before reference, otherwise the parser throws a 400. See the attribute definition requirements here: https://developer.genesys.cloud/api-docs/flow/v2/customattributes.
