Composer.json has incorrect type.

Temporary Workaround

composer require oomphinc/composer-installers-extender

Then in composer.json,

"extra": {
        ...
        "installer-types": ["module"],
        "installer-paths": {
            "web/core": ["type:drupal-core"],
            "web/libraries/{$name}": ["type:drupal-library"],
            "web/modules/contrib/{$name}": ["type:drupal-module"],
            "web/profiles/contrib/{$name}": ["type:drupal-profile"],
            "web/themes/contrib/{$name}": ["type:drupal-theme"],
            "drush/Commands/contrib/{$name}": ["type:drupal-drush"],
            "web/modules/contrib/{$name}": ["type:module"]
        },
        ...
    }

Pushed the changes in the new release tag 1.0.2
