# Firefox issue with @wordpress/interactivity module load

 * I’m building a new Woocommerce site using roots/sage as my base theme (version
   11) and when trying to add a product filter to a product archive page, I’m console
   errors such as:
 * `Uncaught TypeError: The specifier “@wordpress/interactivity” was a bare specifier,
   but was not remapped to anything. Relative module specifiers must start with “./”,“../”
   or “/”. product-filters.js:1:17`
 * I get 4 of these messages in the console and the filters whilst visible are not
   functioning. This only occurs in Firefox as far as I know, I have version 143.0.1.
   In Chrome everything is as it should be.
 * I did come across this thread from a year go with a similar issue – [https://wordpress.org/support/topic/importmap-wordpress-interactivity/](https://wordpress.org/support/topic/importmap-wordpress-interactivity/)
   where [@becleung](https://wordpress.org/support/users/becleung/) suggested it
   was because there is no priority set on the add_action in wp-includes/class-wp-
   script-modules.php. I have however tried adding the suggested code to my theme
   and whilst it gets rid of the original error, it introduces new ones:
 * `Uncaught TypeError: can't access property "symbol", r is undefined

   price.js?ver=b040f78c37f50f902e02:1product-filter-price.js:1:402
 * Does anyone know how to get around this?

 * I recommend getting in touch with WooCommerce’s support about this via [https://woocommerce.com/my-account/contact-support/](https://woocommerce.com/my-account/contact-support/)
   if you have any of their paid WooCommerce products or [https://wordpress.org/support/plugin/woocommerce/](https://wordpress.org/support/plugin/woocommerce/)
   if you do not.

 * It looks like the file `product-filter-price.js` is from a paid product, which
   I don’t have, so I can only guess, I can’t test my theory… but I’m guessing `
   product-filter-price.js` is being loaded too soon.
 * Whatever “r” is, it’s probably defined by some script somewhere on your page,
   and `product-filter-price.js` needs to go after that.
 * My script might be putting `product-filter-price.js` in the header when it’s 
   supposed to be in the footer.
 * So maybe you need to use wp_enqueue_script to put `product-filter-price.js` in
   the footer.
 * Maybe something like this?
 *     ```wp-block-code
       add_action( 'wp_enqueue_scripts', 'enqueue_product_filter_price_after_r' );function enqueue_product_filter_price_after_r() {    wp_enqueue_script('productfilterprice', plugins_url('woocommerce/assets/client/blocks/woocommerce/product-filter-price.js','woocommerce'), array(), '1.2.3', true);}
       ```
   
 * You might have to adjust a few things. Such as the version number is probably
   not “1.2.3”, so put whatever the version number is, instead of “1.2.3”.

 * Thanks so much for having a look at this. [@becleung](https://wordpress.org/support/users/becleung/)
   joy with the script addition above though, adding that to my theme resulted in
   a new error:
 * `Uncaught SyntaxError: import declarations may only appear at top level of a 
   module product-filter-price.js:1:1`
 * I’ll do what [@macmanx](https://wordpress.org/support/users/macmanx/) suggested
   and raise an issue with Woocommerce!

 * Looks like the script type needs to be specified as “module”. Adding this might
   help:
 *     ```wp-block-code
       function set_scripts_type_attribute( $tag, $handle, $src ) {    if ( 'productfilterprice' === $handle ) {        $tag = '<script type="module" src="'. $src .'"></script>';    }    return $tag;}add_filter( 'script_loader_tag', 'set_scripts_type_attribute', 10, 3 );
       ```
