error parsing Deadline: %w

Error message

error parsing Deadline: %w

What it means

DrainConfigFromAgent converts the agent's drain config; when a Deadline is set, time.ParseDuration fails on a malformed duration string, so node drain metadata cannot be translated into the client's DrainConfig.

Solutions

1. Fix the drain deadline in the agent config to a valid duration (e.g. "1h")
2. Validate the deadline before sending the drain spec
