Architect flow deployment CLI throwing 422 on IVR prompt references

Architect & Flows
1

Pushing updated IVR flows through the internal Typer CLI and the deployment endpoint keeps balking at the prompt blocks. The script pulls the latest flow version, swaps out the greeting text, and hits POST /api/v2/architect/flows/{id}/deployments. Console shows the exact same flow deploys fine when pushed manually. CLI gets a hard 422 Unprocessable Entity back.

Environment specs:

  • Python 3.11.6
  • genesys-cloud-python 2.0.158
  • typer 0.9.4
  • Genesys Cloud org region: us-east-1
  • Local build server time: WAT (UTC+1)
  • Flow type: ivr_routing

The response payload points straight at the say block.

{
 "code": "422000",
 "message": "Invalid flow structure. Block type 'say' requires valid 'prompt' reference.",
 "details": [
 "Block 'block_greeting_ivr' references prompt 'prompt_88a2c1' which failed validation."
 ]
}

The prompt ID checked out. It’s active, assigned to the correct language locale, and the CLI actually fetches it via GET /api/v2/architect/prompts/{id} before injecting it into the flow JSON. SDK serialization looks clean. Even dumped the raw request body and compared it byte-for-byte with a successful manual deployment from the browser dev tools. Only difference is the flow_version timestamp field. CLI sends the exact ISO string the version endpoint returned.

Forcing a flow_version override in the deployment payload yielded the same 422. Stripping the metadata field from the flow object produced the same result. The Click group handling the deployment command just spits out the error and exits. Build pipeline stalled since 02:30 local time.

Below is the minimal Typer command structure handling the push:

@app.command()
def deploy_ivr(flow_id: str, prompt_id: str):
 client = get_gc_client()
 versions = client.flow_versions.get_flow_versions(flow_id=flow_id)
 latest = versions.body[0]
 
 flow_data = latest
 flow_data["blocks"]["block_greeting_ivr"]["prompt"]["id"] = prompt_id
 
 try:
 resp = client.deployments.post_architect_flow_deployments(
 flow_id=flow_id,
 body={"flow_version_id": latest["id"], "flow": flow_data}
 )
 click.echo(f"Deployed: {resp.body['id']}")
 except Exception as e:
 click.echo(f"Deployment failed: {e}")

The flow field in that deployment payload might be the culprit. Docs say it’s optional if flow_version_id is provided, but the CLI sends both to force the prompt override. API seems to validate the full flow object against the version hash. Hash mismatch triggers the 422. Not sure if there’s a way to patch just the prompt reference without rebuilding the whole flow version object.
Logs show the request hits the gateway, times out on validation, and drops.

{
 "type": "prompt",
 "promptId": "a1b2c3d4-5678-90ab-cdef-1234567890ab",
 "playMode": "sequential",
 "timeoutSeconds": 30,
 "retries": 1
}

The deployment endpoint expects that exact shape. Custom CLIs don’t preserve the nested defaults during JSON serialization. When playMode or timeoutSeconds drops out, the parser throws a 422 before it even hits the state engine.

Patch the payload builder to enforce the schema:

def patch_prompt_blocks(flow_def):
 for block in flow_def.get("blocks", []):
 if block.get("type") == "prompt":
 block.setdefault("playMode", "sequential")
 block.setdefault("timeoutSeconds", 30)
 block.setdefault("retries", 1)
 return flow_def

Run the flow JSON through that right before the POST. The API validator doesn’t play nice with partial prompt objects. Manual deploys work because the UI auto-fills those fields. State drift happens fast with custom push scripts. Network tab capture usually shows the exact shape. Patch the serializer.
