Invalid webpack stats structure, please make sure webpack stats configuration is correct.

[eloisetaylor5693]

Get an error when using the github action task. Looking at the webpack.stats.json file, it looks valid. I'm also building before running the task.

Is there something missing from the config? Or is there a bug in the package?

Error:

Run vio/bundle-stats-action@v1.3.0
  with:

Warning: Invalid webpack stats structure, please make sure webpack stats configuration is correct.

Hi @eloisetaylor5693, thanks for opening the issue!

I'm also building before running the task.

This is a very common workflow, i think your setup looks ok

Based on the error you are getting and the structure of the webpack stats, the output is missing { assets: [], modules: [] }. What method/stats config are you using to output the webpack stats?

If you get the chance, can you please try to use https://github.com/relative-ci/bundle-stats/tree/master/packages/cli#webpack-configuration ?

[eloisetaylor5693]

Initially I was using the short syntax with no config overrides. Then I used the stats options from the link you sent. The same error is generated

Previous gatsby.config:

module.exports = {
     ....
     plugins: [
     ....
          `gatsby-plugin-bundle-stats`,
     ]
}

New gatsby.config:

(I tried only setting assets and modules flags first, but that didn't work so added the other settings too)

module.exports = {
     ....
     plugins: [
     ....
          {
              resolve: "gatsby-plugin-bundle-stats",
              options: {
                stats: {
                  context: './src',
                  assets: true,
                  modules: true,
                  entrypoints: true,
                  chunks: true,
                  builtAt: true,
                  hash: true,
                },
              },
            },
     ]
}

Resulting webpack.stats.json after the build:

@eloisetaylor5693 gatsby-plugin-bundle-stats and bundle-stats-action are two different ways of generating the bundle-stats report. The configuration for gatsby-plugin-bundle-stats is affecting only the way the plugin is reading the stats from webpack and is not affecting the output of the webpack stats from your compilation.

What method are you using to output webpack.stats.json file that you pass to bundle-stats-action?

[eloisetaylor5693]

I'm not customising the webpack config at all, so using the default gatsby config. It's all under the hood because there's 0 results when searching for webpack in my repo (save for package.json)

This is the Gatsby starter I used to generate my project: https://github.com/gatsbyjs/gatsby-starter-blog

@eloisetaylor5693 the webpack stats produced by Gatsby by default does not contain the information that bundle-stats requires in order to generate the report.

You can try to customize the Gatsby webpack stats config or you can try to use webpack-stats-plugin and generate another webpack stats file:

// gatsby-node.js
const { StatsWriterPlugin } = require('webpack-stats-plugin');

exports.onCreateWebpackConfig = ({ stage, plugins, actions }) => {
  if (stage === 'build-javascript') {
    actions.setWebpackConfig({
      plugins: [
        new StatsWriterPlugin(
          filename: 'stats.json',
          stats: {
            context: './src', // optional, will improve readability of the paths
            assets: true,
            entrypoints: true,
            chunks: true,
            modules: true
          }
        )
      ]
    });
  }
};
