Function Compute:What do I do if a function times out with the error "Function time out after"?

Last Updated:Feb 28, 2026

Problem

Function invocations occasionally fail with the error Function time out after.

Solutions

Try the following solutions to diagnose and resolve the issue.

Solution 1: Increase the Execution Timeout

The function may require more time than the current timeout allows. Increase the Execution Timeout for the function.

For more information, see Manage functions.

Solution 2: Check the function logic and configure logging

Check the function logic and configure logging for the function. Review the logs to determine whether the timeout coincides with a call to another API operation. Latency or delays in outbound API calls are a possible cause of timeouts.

Solution 3: Check for CPU-intensive code paths

Examine whether the function contains computationally expensive code paths, such as CPU-intensive operations. Certain input conditions can trigger heavier processing and cause the function to exceed its timeout.
