Python SDK token refresh not triggering in long-running worker

Running a Node.js worker that polls Genesys Cloud every minute. The token expires and I start getting 401s immediately. The SDK is supposed to handle refresh automatically but it’s just failing hard instead of retrying. Am I missing a config flag?

Node isn’t really my wheelhouse, but the logic for token handling is usually identical across SDKs. If you’re seeing immediate 401s without a retry, the automatic refresh mechanism is likely broken or not being awaited correctly.

In Python, I usually avoid relying solely on the background thread for critical long-running workers. It’s safer to explicitly check the token status or wrap the call in a retry loop that catches the specific Unauthorized exception. The SDK’s PureCloudPlatformClientV2 has a refresh_token method you can call manually if the auto-refresh fails.

Here is how I handle it in a worker to ensure we don’t just crash on expiration:

from purecloudplatformclientv2 import PureCloudPlatformClientV2, ApiClient, ApiException
import time

# Initialize client
platform_client = PureCloudPlatformClientV2()
platform_client.set_access_token(ACCESS_TOKEN, REFRESH_TOKEN, CLIENT_ID, CLIENT_SECRET)

def safe_api_call():
 while True:
 try:
 # Your actual API call here
 # e.g., api_instance = ConversationApi(platform_client)
 # response = api_instance.get_conversations()
 return True 
 except ApiException as e:
 if e.status == 401:
 print("Token expired or invalid. Forcing refresh...")
 try:
 # Explicitly trigger refresh
 platform_client.refresh_token()
 print("Refresh successful. Retrying...")
 time.sleep(1) # Small delay to let propagation settle
 except Exception as refresh_err:
 print(f"Refresh failed: {refresh_err}")
 return False
 else:
 # Handle other errors
 raise e

# Run your worker loop
while True:
 if not safe_api_call():
 break
 time.sleep(60)

The key is catching the 401 explicitly. The auto-refresh in the background can sometimes get out of sync if the worker is idle for a while or if there’s a network hiccup during the refresh request. Forcing the refresh on a 401 gives you more control.

Also check your REFRESH_TOKEN expiry. If that’s expired, no amount of retrying will help. You’ll need to re-authenticate.

I’ve seen this happen when the clock on the worker machine drifts too far from the Genesys servers. JWT validation fails hard in that case. Sync your NTP.
