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.
