`deno task start` fails on newly created project

[mbhrznr]

steps to reproduce:

1. create a new ultra project w/:

   deno run -A -r https://deno.land/x/ultra/create.ts

2. build the project w/:

   deno task build

3. navigate into the build dir and try to serve the project:

   cd .ultra/ && deno task start

the following error pops up:

Task start ULTRA_MODE=production deno run -A --no-remote ./server.js
error: Uncaught SyntaxError: The requested module 'react-dom/server' does not provide an export named 'renderToString'
import { renderToString } from "react-dom/server";

taking a look at the .ultra directory and especially at importMap.server.json it looks like there's a mismatch in the linked dependencies:

{
  "imports": {
    "./server.tsx": "./server.js",
    "./src/app.tsx": "./src/app.c8559919.js",
    "https://deno.land/": "./vendor/server/deno.land/",
    "https://esm.sh/": "./vendor/server/esm.sh/",
    "react/jsx-runtime": "./vendor/server/esm.sh/stable/react@18.2.0/deno/react.mjs",
    "ultra/server.ts": "./vendor/server/deno.land/x/ultra@v2.3.1/server.ts",
    "ultra/hooks/use-asset.js": "./vendor/server/deno.land/x/ultra@v2.3.1/hooks/use-asset.js",
    "react": "./vendor/server/esm.sh/stable/react@18.2.0/deno/react.mjs",
    "react-dom/server": "./vendor/server/esm.sh/stable/react@18.2.0/deno/react.mjs"
  },
  "scopes": {
    "./vendor/server/deno.land/": {
      "/std@0.176.0/": "./vendor/server/deno.land/std@0.176.0/",
      "/std@0.97.0/": "./vendor/server/deno.land/std@0.97.0/",
      "/x/": "./vendor/server/deno.land/x/"
    },
    "./vendor/server/esm.sh/": {
      "/stable/": "./vendor/server/esm.sh/stable/"
    }
  }
}

rather than linking to react-dom/server, esm.sh seems to link to react again, thus failing to find the import.

i assume the underlying issue could also be caused by esm.sh?

Thanks for reporting! I think it could be due to the fact that esm.sh changed how it handles waterfall dependencies and the wrong module is being detected during the build

[deckchairlabs]

Could you try the latest release? You should only need to update your import map for ultra

[mbhrznr]

works like a charm! thank you so much for the quick fix!
