Help

I am not getting request from the context, this is my server file.

export async function buildTestServer({
  user,
  headers,
  roles,
}: {
  user?: User;
  headers?: { [key: string]: string };
  roles?: Role;
}) {
const server = new ApolloServer({
    schema,
    context: async ({ req }) => {
      const authHeader = headers?.authorization;
        const token = extractTokenFromAuthenticationHeader(authHeader);
        try {
          const user = await new UserPermissionsService(token).call();
          return { req, user };
        } catch {
          return { req };
        }
}

And this is my test file from where I building the server and calling the resolver to test, but I am not getting the request.

const GET_LIST = `
query GetList($listId: String!) {
  GetList(listId: $listId) {
    id
  }
}
`;

test('Get Lists', async () => {
  const customer = await CustomerFactory.create();
  const user = await UserFactory.create({ customerId: customer.id });
  const list = await ListFactory.create({
    customerId: customer.id,
  });
  const server = await buildTestServer({ user });
  const result = await server.executeOperation({
    query: GET_LIST,
    variables: {
     listId: list.id
    },
  });
  console.log("check list error", JSON.stringify(result));
  var length = Object.keys(result.data?.GetLists).length;
  expect(length).toBeGreaterThan(0);
});
