Describe the bug

Trying RPCE for the first time and using the simple starter snippet from the Usage section.
When I run rollup -c I am getting this cryptic error:

> rollup -c --validate

manifest.json → build...
[!] (plugin chrome-extension) Error: EISDIR: illegal operation on a directory, read
Error: EISDIR: illegal operation on a directory, read

I tried both on Windows and on Linux (mac).

This is my rollup.config.js:

import resolve from '@rollup/plugin-node-resolve'
import commonjs from '@rollup/plugin-commonjs'

import { chromeExtension, simpleReloader } from 'rollup-plugin-chrome-extension'

export default {
    input: 'manifest.json',
    output: {
        dir: 'build',
        format: 'esm',
    },
    plugins: [
        // always put chromeExtension() before other plugins
        chromeExtension(),
        simpleReloader(),
        // the plugins below are optional
        resolve(),
        commonjs(),
    ],
}

My manifest.json is standard as well:

{
  "manifest_version": 2,
  "permissions": [
    ...
  ],
  "background": {
    "scripts": [
      "background_script/background.js"
    ]
  },
  "content_scripts": [
    {
      "matches": [
        "https://website.com/*"
      ],
      "js": [
        "content_script/content.js"
      ],
      "css": [
        "content_script/css/style.css"
      ]
    }
  ],
  "browser_action": {
    "default_title": "title",
    "default_icon": {
      "16": "static/icons/16.png",
      "32": "static/icons/32.png"
    }
  },
  "icons": {
    "16": "static/icons/16.png",
    "32": "static/icons/32.png",
    "48": "static/icons/48.png",
    "128": "static/icons/128.png"
  },
  "web_accessible_resources": [
    "static/*"
  ]
}

What should I investigate?

Reproduction

Severity

blocking all usage of RPCE

Hard to say without more info. The manifest looks good. It seems that Rollup is trying to read a directory as a file.

What version of RPCE are you using?

[amiregelz]

The latest, tried both beta and stable

[jacksteamdev]

@amiregelz I've done a major rewrite, would you mind giving it a try?

The API has changed a little, you can see the updated instructions on DEV:

i had the same problem as amiregelz and after following your vite-react tutorial it now works.
it didn't work right away though, only after these two changes:

• migrate from manifest version 2 to 3
  with manifest version 2, i got this error:
  
  which i think occurs at this point in the code because web_accessible_resources is assumed to be a list of objects rather than a list of strings as per MV3.
• moving all of my icons to the toplevel ./public folder as suggested here

now it works like a charm!

@jacksteamdev can i also just say that your blog post and comments are such a joy to read. i find them very comprehensible and user friendly. thank you for the effort you put into it all :)

[jacksteamdev]

@flurrux Thanks for your kind words! Comments like yours make all the difference. 🤗

We probably need to add some validation, since manifest version 2 isn't supported.

[jacksteamdev]

Added MV3 validation in #258

[jacksteamdev]

moving all of my icons to the top-level ./public folder as suggested

Added auto-copy for missing manifest assets in #259

It appears that this issue is now primarily a duplicate of #137, closing
