fetch-static.ts:27:23 - error SC2020: 'Response.arrayBuffer in a static build' is part of the standard library types but has no scriptc lowering yet

     |                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  hint: the native static Response surface is status/ok/statusText/url/redirected/headers/body/bodyUsed plus json(), text(), bytes(), and arrayBuffer(); use --dynamic for the wider Web API
