Script translation through load_script_translations

[giuliodelmastro]

Good morning! I'm experiencing some problems with the translation of my plugin and I can't seem to get to the bottom of it!

My plugin is completely custom, it's an quote-generator for a client of mine.

I used @wordpress/scripts to develop the form that is displayed on the fronted I used @wordpress/element. The rendering is through react.

It is not a block as my client is still using shortcodes.

I created the po and mo files, through Poedit. Both files are generated correctly. On the admin side where I display a wp-list-table there are no problems, the translation is loaded and displayed correctly.

Fronted side on the form instead I use @wordpress/i18n (__()) for translations.

I then created with wp cli wp i18n make-json languages the json.

Here I encounter the first problem, only 4 of the strings in the .po file are displayed.

When I then use wp_set_script_translations (which returns true) the json file is not loaded on the fronted.

`
foreach ($this->get_scripts() as $script) {

        wp_register_script(
            $script->get_handle(),
            $script->get_src(),
            $script->get_deps(),
            $script->get_ver(),
            [
                'strategy' => $script->get_strategy(),
                'in_footer' => $script->get_in_footer()
            ]
        );

        wp_enqueue_script(
            $script->get_handle()
        );


        load_script_translations(CERTIBRASIL_PLUGIN_PATH . 'languages/certibrasil-pt_BR.json', $script->get_handle(), 'certibrasil');
    }

`

I anticipate that I use wp_set_script_translations after queuing the script, and the script has i18n as a dependency.

Where could the problem be?
