Solutions

1. Lower timeoutMs to at most the maximum Node timer delay.

When it happens

Trigger: Thrown at packages/web/web-fetch-http/src/index.ts:72 when the library encounters an invalid state.

Common situations: See trigger scenarios.

Understand the failure class

• Timeouts: ETIMEDOUT, deadlines, and hung requests — what actually expires when a request times out.
