Issues migrating dependencies from v1.x to v2.x

Hey, I'm facing some issues when upgrading from v1.146 to v2.

We have a backend monorepo that uses 
import_map.json
 files to manage dependencies per sub module in our monorepo. We don't have a package.json for Deno (only for our Next.js frontend which is still on node). We do have a 
deno.jsonc
 at the root level of our project. After upgrading to Deno v2, we get these errors when we run or try to install:
# install
error: Error in @stripe/react-stripe-js@3.1.0 parsing version requirement for dependency "react-dom": ">=16.8.0 && <=^19.0.0"
deno install
Caused by:
    0: Invalid version requirement
    1: Unexpected character.
         >=16.8.0 && <=^19.0.0
         ~


# run
Running  service
Watcher Process started.
error: Could not find a matching package for 'npm:pg@8.12.0' in the node_modules directory. Ensure you have all your JSR and npm dependencies listed in your deno.json or package.json, then run `deno install`. Alternatively, turn on auto-install by specifying `"nodeModulesDir": "auto"` in your deno.json file.

error: [ERR_MODULE_NOT_FOUND] Cannot find module 'file:///Users/app/node_modules/type-fest/index.js' imported from 'file:///Users/app/@types/date.types.ts'
    at file:///Users/app/@types/date.types.ts:8:24


this is part of our import_map.json file:
{
  "imports": {
    "kysely": "https://esm.sh/kysely@0.27.5",
    "pg": "npm:pg@8.12.0",
    "query-string": "https://esm.sh/query-string@9.1.1?dts",
    "remeda": "https://esm.sh/remeda@2.17.4?dts",
    "stripe": "https://esm.sh/stripe@17.4.0?dts",
    "type-fest": "npm:type-fest@4.30.1",
    "zod": "https://deno.land/x/zod@v3.24.1/mod.ts"
  }
}


What is the proper way to step Deno dependencies for v2 in a monorepo, and should we keep using import maps?
