Error: The deployment failed: Relative import path "$fresh/server.ts" not prefixed with / or ./ or ../

[ooker777]

When deploying I get this error:

Deploying... (100.0%)
Error: The deployment failed: Relative import path "$fresh/server.ts" not prefixed with / or ./ or ../

A person who had the same error on their machine solves this by adding this to the import map:

  "deno.importMap": "./import_map.json"

This doesn't work on my case. In my understanding this shouldn't be an issue at all. Do you know why is that?

Background

My fresh project is under some sub-folder from the root. The structure is like this:

    └── 1/
        └── Web/
            ├── main.ts
            └── dev.ts

Check if with deployctl@v1 you don't need to exclude: "node_modules" (not by default for older version)

    - name: Upload to Deno Deploy
        uses: denoland/deployctl@v1
        with:
          project: "xxx" 
          entrypoint: "./main.ts"
          exclude: "node_modules"

Still get the same error

Make sure that the path to your main.ts or dev.ts doesn't have space or non-ASCII characters. I haven't figured out how to escape them.
