Under the Vitest fork pool it can win the shared global dispatcher symbol before this package's undici loads, so getGlobalDispatcher() returns a cross-version wrapper whose handler hides the request opaque from our diagnostics_channel instrumentation. That silently broke request timing and socket tracing in tests (timing/diagnostics/keepalive/redirect). Add a Vitest setup file that resets the global dispatcher to this package's own undici Agent when the current one is not an undici Dispatcher instance, matching real-world usage where undici wins the global dispatcher symbol. Production code is unaffected. --- test/setup.ts | 17 +++++++++++++++++ vite.config.ts | 1 + 2 files changed, 18 insertions(+) create mode 100644 test/setup.ts diff --git a/test/setup.ts b/test/setup.ts new file mode 100644 index 00000000..fb25f679 --- /dev/null +++ b/test/setup.ts @@ -0,0 +1,17 @@ +import { Agent, Dispatcher, getGlobalDispatcher, setGlobalDispatcher } from 'undici'; + +// On Node.js >= 26 the runtime ships its own (newer) built-in undici.
