Sourcemaps are always tryed to be fetched from production url

Hi, I’m getting stuck this last week trying to make that errors shown at sentry shows the stack trace correctly (without being minified).

We are working with a self-hosted sentry instance (8.18.0 version). We use the sentry-webpack plugin to upload the artifacts.
We have set in like this:

new SentryWebpackPlugin({
release: config.versionWithExtraInfo,
include: ‘dist’,
ignore: [‘node_modules’, ‘webpack.config.js’],
configFile: ‘…/.sentryclirc’,
debug: true,

Release version matches, I already checked that.

I really dont understand why sentry tries to fetch the source map from the production url instead from artifacts.
