Textures missing after build Phaser game

[MEJSIK]

After build my Phaser Game, i don't see my multiatlas called 06mapa in game.textures.list (screens below):
DEV:

Prod (after npm run build):

I think it's loading properly, but why it is not available on production?

Phaser itself has no concept of a 'production' build (or indeed a build at all), so you need to look to your tooling to figure out why it's being stripped from the bundle.

I use Webpack as my bundletool. But I think it's not Webpack's problem. It's weird. I think it's problem with loading .json files into Phaser, because this function isn't loading all of my assets from my json file.
That's original assets.json file:

And that's after build:

I use script to load my assets from .json file:

private loadAssets(json){
      Object.keys(json).forEach(function (group)
      {
          Object.keys(json[group]).forEach(function (key)
          {
              let value = json[group][key];

              if (group === 'atlas' ||
                  group === 'unityAtlas' ||
                  group === 'bitmapFont' ||
                  group === 'spritesheet' ||
                  group === 'multiatlas')
              {

                  // atlas:ƒ       (key, textureURL,  atlasURL,  textureXhrSettings, atlasXhrSettings)
                  // unityAtlas:ƒ  (key, textureURL,  atlasURL,  textureXhrSettings, atlasXhrSettings)
                  // bitmapFont ƒ  (key, textureURL,  xmlURL,    textureXhrSettings, xmlXhrSettings)
                  // spritesheet:ƒ (key, url,         config,    xhrSettings)
                  // multiatlas:ƒ  (key, textureURLs, atlasURLs, textureXhrSettings, atlasXhrSettings)
                  this.load[group](key, value[0], value[1]);

              }
              else if (group === 'audio')
              {

                  // do not add mp3 unless, you bought a license 😉
                  // opus, webm and ogg are way better than mp3
                  if (value.hasOwnPorperty('opus') && this.sys.game.device.audio.opus)
                  {
                      this.load[group](key, value['opus']);

                  }
                  else if (value.hasOwnPorperty('webm') && this.sys.game.device.audio.webm)
                  {
                      this.load[group](key, value['webm']);

                  }
                  else if (value.hasOwnPorperty('ogg') && this.sys.game.device.audio.ogg)
                  {
                      this.load[group](key, value['ogg']);

                  }
                  else if (value.hasOwnPorperty('wav') && this.sys.game.device.audio.wav)
                  {
                      this.load[group](key, value['wav']);
                  }
              }
              else if (group === 'html')
              {
                  // html:ƒ (key, url, width, height, xhrSettings)
                  this.load[group](key, value[0], value[1], value[2]);

              }
              else
              {
                  // animation:ƒ (key, url, xhrSettings)

          }, this);
      }, this);

It's definitely a webpack issue. As I said, Phaser really has no concept of 'dev' vs. 'prod' - it literally cannot act differently between the two, because it has no notion that it is in a 'dev' or 'live' state.

All it knows is that you've given it a list of assets to load. So it tries to load them, as long as they are present and it can access them. Perhaps webpack has a setting that only includes files below a certain file size? I.e. the bundle has gotten too large for it?

Also, check in Dev Tools network panel, and see if the files are in there - because they should be.
