UDS Intermittent Timeout Failure

UDS Intermittent Timeout Failure

Issue Description

The provider is invoking our UDS (Universal Data Sync) flow; however, the requests are failing intermittently due to a timeout.

This occurs when the provider does not send a response within the configured action timeout duration.

Root Cause

The Action Timeout defines the maximum duration within which the provider must respond to the UDS request.

  • UDS is configured to retry the request 3 times if no response is received.

  • If the provider fails to respond within the configured timeout during all three attempts, the request ultimately fails.

  • For example, if the logs show a timeout at 31 seconds, this indicates:

    • The action timeout was set to 10 seconds

    • UDS retried 3 times

    • Total elapsed time ≈ 30 seconds (plus processing overhead)

Resolution Steps

To increase the timeout limit:

  1. Open the UDS Flow

  2. Click on Edit

  3. Navigate to Advanced Options

  4. Increase the Action Timeout limit

  5. Save and publish the changes


Important Notes

  • The Action Timeout should be configured based on the provider’s average response time.

  • If the provider consistently takes longer to respond, they should optimize their response time.

  • Increasing the timeout temporarily can help mitigate intermittent failures, but the long-term fix should ensure the provider responds within the configured limit.
