+Fix error when fetching data on `vite-node` environment by setting a global variable `TW_SKIP_FETCH_SETUP` to `true`. Fixes https://github.com/thirdweb-dev/js/issues/2002
+
+Setting this flag sets `skipFetchSetup` to `true` in [ethers ConnectionInfo](https://docs.ethers.org/v5/api/utils/web/#ConnectionInfo)
+
+```ts
+// set this global variable
+globalThis.TW_SKIP_FETCH_SETUP = true;
+
+// use the thirdweb sdk...
+```
