Unable to deploy function

[FaludaAndIce]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

The Supabase CLI consistently fails to deploy an Edge Function that imports modules from Deno's standard library (std/server) and @supabase/supabase-js, reporting a "Module not found" error for the standard library module, even when a correctly formatted deno.json import map is present in the function's directory and explicitly referenced in config.toml or via the --import-map flag.

To Reproduce

Steps to reproduce the behavior:

1. Initialize a Supabase project and create a new Edge Function named check-user-existence using the Supabase CLI.

2. Replace the contents of supabase/functions/check-user-existence/index.ts with the following code:

   // Setup type definitions for built-in Supabase Runtime APIs
   import "jsr:@supabase/functions-js/edge-runtime.d.ts";
   
   import { serve } from 'std/server';
   import { createClient } from '@supabase/supabase-js';
   
   const supabaseUrl = Deno.env.get('SUPABASE_URL')!;
   const supabaseServiceKey = Deno.env.get('SERVICE_ROLE_KEY')!;
   
   const supabaseClient = createClient(supabaseUrl, supabaseServiceKey, {
     auth: {
       persistSession: false,
     },
   });
   
   serve(async (req: Request) => {
     if (req.method !== 'POST') {
       return new Response('Method Not Allowed', { status: 405 });
     }
     try {
       const { email }: { email?: string } = await req.json();
       if (!email) {
         return new Response(JSON.stringify({ error: 'Email is required' }), { status: 400, headers: { 'Content-Type': 'application/json' } });
       }
       const { data, error } = await supabaseClient.auth.admin.getUserByEmail(email);
       const exists = data !== null;
       return new Response(JSON.stringify({ exists }), { headers: { 'Content-Type': 'application/json' } });
     } catch (error) {
       return new Response(JSON.stringify({ error: 'Internal Server Error' }), { status: 500, headers: { 'Content-Type': 'application/json' } });
     }
   });

3. Create a deno.json file in the supabase/functions/check-user-existence directory with the following content:

   {
     "imports": {
       "std/": "[https://deno.land/std@1.42.0/](https://deno.land/std@1.42.0/)",
       "@supabase/supabase-js": "[https://esm.supabase.com/supabase-js@2](https://esm.supabase.com/supabase-js@2)"
     }
   }

4. Ensure your config.toml file in the project root has the following configuration for the function:

   [functions.check-user-existence]
   enabled = true
   verify_jwt = true
   import_map = "./supabase/functions/check-user-existence/deno.json"
   entrypoint = "./supabase/functions/check-user-existence/index.ts"

5. Attempt to deploy the function using the command: supabase functions deploy check-user-existence from the project root.

6. Observe the error: Error: failed to create the graph Caused by: Module not found "https://deno.land/std@1.42.0/server/mod.ts" ... Relative import path "std/server" not prefixed with / or ./ or ../ and not in import map ...

Expected behavior

The Edge Function should be bundled and deployed successfully, resolving the std/server and @supabase/supabase-js modules using the deno.json import map.

System information

• OS: macOS Sonoma 14.4.1
• Browser (if applies): N/A
• Version of supabase-js: (Implicitly used by the Edge Function runtime)
• Version of Node.js: v20.11.0
• Version of Supabase CLI: 2.20.3

Additional context

I have tried numerous variations of the deno.json file (including explicit mapping of std/server/mod.ts), using the --import-map flag directly in the deploy command, and reinstalling the Supabase CLI. The issue persists across all attempts. The CLI seems unable to correctly load or utilize the deno.json import map to resolve the Deno standard library modules. The @supabase/functions-js/edge-runtime.d.ts import also doesn't seem to be recognized as being in the import map.

Running with --debug shows lines like:
DEBUG Specifier "std/server" was not mapped in import map.
DEBUG Specifier "jsr:@supabase/functions-js/edge-runtime.d.ts" was not mapped in import map.

This suggests the import map is not being processed correctly during the graph creation phase of the deployment.

Literally all i want is a simple edge function to check if an email exists before i navigate the user to sign up or login (if email exists). But have spent 2 hours trying to setup the Supabase CLI and deploying a function... not a lot of documentation on it that I can find in Supabase docs unfortunately. I'm a beginner to coding as well

[Hallidayo]

Hi @FaludaAndIce - Are you still experiencing this issue on the most recent of the cli?

[AndryHTC]

Yes. It's a problem that has existed for a loooong time. I've even tried to search for it, but I don't have the time, and I'm honestly tired of this.

Move the import map into a file import_map.json. Reference it in the deno.json as the following:

{
  "importMap": "./import_map.json",
  "nodeModulesDir": "auto"
}

As this, it works but while developing it warns you are using the import map the "old way". I'm tired guys

[Hallidayo]

Hi all, I've moved this over to the cli repo

[Soumojit-007]

Remove the import :- import "jsr:@supabase/functions-js/edge-runtime.d.ts
import {serve} from Deno's stdlib to direct CDN import
Keep the supabase client import but using esm.sh instead of JSR
I hope this will work....
