Problem

Logs show an error of:

DagsterUserCodeUnreachableError: Timed out waiting for call to user code GET_EXTERNAL_SENSOR_EXECUTION_DATA

Possible cause

This error usually means the agent is timing out before it can serve the sensor request. It often indicates some kind of resource limit being hit in the agent pod specifically—for example, not enough CPU or not enough threads to work with. It can also indicate that it hit some error preventing it from sending a response.

Solution

• See the Troubleshooting sensor timeouts guide.

• In the 1.7.6 agent release, you can set the agentMetrics.enabled flag to give you more detailed metrics to help with debugging.
