# Importing @vonage/server-sdk causes error TS2694: ConversationAction / StreamAction has no exported member

## The problem

With `@vonage/server-sdk` installed, importing `Vonage` from `@vonage/server-sdk` in a TypeScript project produces errors inside the SDK's own type files: `error TS2694: Namespace .../@vonage/voice/dist/types has no exported member 'ConversationAction'` and the same for `StreamAction` in Stream.d.ts. The project had `skipLibCheck` explicitly set to `false` in tsconfig.json. Reported against server-sdk 3.7.x with Node 20.

## The verified fix

The errors come from type-checking the SDK's bundled `.d.ts` files. Vonage's supported setup is `skipLibCheck: true` in tsconfig.json; setting it to false surfaces internal typing mismatches in `@vonage/voice` (e.g. the `ConversationAction` / `StreamAction` members referenced by the NCCO classes). Turn `skipLibCheck` back on and the errors disappear. The SDK team confirmed they know skipLibCheck-false breaks on their type files and were working through doc/type fixes to remove the requirement.
