Virtual path with gatsby development

[MrGlox]

Description

When running "gatsby develop" after the latest MAJ, the development bundle seems to fail because of a wrong path parsing. This is blocking for deployment and build purpose.

Steps to reproduce

Just run gatsby develop.

Expected result

The dev build should works. Like this quick fix : #25720 (comment)

Actual result

There is the error about the build.

Reference

As asked by @pieh there is the whole discussion #25720

Thank you in advance for your hard work !

Do you use custom eslint setup? Possibly with gatsby-plugin-eslint? If so - could you share your eslint configuration?

[MrGlox]

There is the .eslintrc and yes we use gatsby-plugin-eslint in dev purpose.

{
  "parser": "babel-eslint",
  "rules": {
    "quotes": ["error", "single", { "avoidEscape": true }],
    "indent": ["error", 2],
    "react/jsx-curly-spacing": [
      2,
      { "when": "always", "spacing": { "objectLiterals": "never" } }
    ],
    "object-curly-spacing": ["error", "always", { "objectsInObjects": false }]
  },
  "extends": [
    "eslint:recommended",
    "plugin:react/recommended"
    // "plugin:mdx/recommended"
  ],
  "settings": {
    "import/resolver": {
      "alias": [
        ["assets", "./src/components"],
        ["components", "./src/components"],
        ["containers", "./src/containers"],
        ["contexts", "./src/contexts"],
        ["utils", "./src/utils"]
      ]
    },
    "react": {
      "pragma": "React",
      "version": "latest"
    }
  },
  "env": {
    "browser": true,
    "jest": true,
    "node": true
  }
}

It looks like this is pretty much same problem as one described in #26319 (comment), so idea of adjusting "virtual path" to include .cache for those autogenerated modules probably will fix it (as gatsby-plugin-eslint already ignores .cache).

Thanks for the eslint config - this should make it much easier for me to reproduce

[MrGlox]

Perfect, it works ! I close this one because it's already handled in the linked post ! Thank you again for your reactivity, I'm waiting for your update !

[pieh]

Perfect, it works !

By this - do you mean that you tried the change from PR ( #26396 ) locally?

I did manually test my change after I reproduced the problem using gatsby-plugin-eslint and your .eslintrc config, but that was very simple reproduction case

[MrGlox]

Yes I added this code to my .eslintrc

{
  ...,
  ignorePatterns: ["sync-requires.js", "**/_this_is_virtual_fs_path_/**/*.js"]
}
