fs: Forbidden path on readFile on app restart

[arun-mani-j]

Hii
In my app, I let the user open a file using open from Dialog API. Then I store the obtained path in a database.

Now, if I use the path as it is and try to read it using readFile from File System API, it works fine.

However, once I close the app and re-run it, I get Forbidden path: /path/to/file error when trying to read it. I have already installed Persisted Scope and have this in my capabilities/default.json:

{
  "$schema": "../gen/schemas/desktop-schema.json",
  "identifier": "default",
  "description": "enables the default permissions",
  "windows": ["main"],
  "permissions": [
    "core:default",
    "dialog:default",
    {
      "identifier": "fs:allow-read-file",
      "allow": [{ "path": "*" }]
    }
  ]
}

Can someone help me understand what I'm missing?

Can you also share the output of the the tauri info command and the rust code where the persisted scope plugin is initialized? This is exactly what the plugin was created for so it's a bit weird that it's not working.

Also, while we of course don't recommend it, try "allow": [{ "path": "*" }, { "path": "**/*" }] instead as a workaround while the plugin doesn't work for you. * / ** don't match nested files so your current config isn't working.

Thanks, I think I found out why I'm getting this error.

I tried a fresh Tauri app and installed, dialog, fs and scope plugins there. There it worked fine 🫠.

So I tried to debug what's happening in my original app.

1. Running tauri info showed that the plugins in original app were stuck at 2.0 but the fresh app used 2.2 variants.
2. So I updated both JS and Cargo packages (npx npm-check-updates -u and cargo update).
3. Then after running the original app, I got this message in console: Please make sure to register the fsplugin before thepersisted-scope plugin!.
4. So I opened src-tauri/src/lib.rs in both fresh and original apps.
5. In fresh app, persisted scope was loaded after fs plugin but in original app, it was loaded before fs and dialog plugin.
6. So I changed the order in the original app and now it is working fine.

Weird thing is, I never touched lib.rs before, so don't know how the order changed... 😅
