It also depends on the version of CopyWebpackPlugin… Phoenix use 5.x syntax, but if You are using 6.x branch of the webpack plugin, You need to update webpack.config.js to…
# old syntax
new CopyWebpackPlugin([{ from: "static/", to: "./" }]),
# new 6.x syntax
new CopyWebpackPlugin({
patterns: [{ from: "static/", to: "./" }]
}),
This plugin is in charge of copying what is in assets/static to priv/static. You should not touch priv/static, and just put into assets/static
