When does this happen?

IF Upgrading the TypeScript SDK to v1.25.0 causes global.fetch to be replaced by an anonymous wrapper, breaking all fetch calls.

How others solved it

THEN Upgrade the @hono/node-server dependency to the latest version, which no longer overrides global.fetch. If immediate upgrade is not feasible, pin the SDK version below 1.25.0 or apply a post-import patch to restore the original global.fetch.

// Problematic override from @hono/node-server (see issue #1376):
// global.fetch = (info, init) => { ... }. Upgrade to fix.
