taxonomy – update_term_meta not working

I’m making an attempt to take away a string off of a bunch of slugs in phrases from a CPT taxonomy.

For instance, I’ve a time period named “Accounting” however the slug has the “accounting-expert-witnesses” I simply have to take away the “-expert-witnesses” a part of the slug.

I’m utilizing this put up as a reference because it seems to be what am I on the lookout for however I can’t appear to get any of the ideas to work: Methods to replace taxonomy customized subject with wp_update_term()?

I’ve tried utilizing update_term_meta, update_post_meta, wp_update_term and none of them are doing what I would like.

The closest I’ve bought is utilizing update_term_meta and it seems to be working once I error log the end result nevertheless once I have a look at the phrases within the dashboard nothing has been up to date.

I am unable to work out what I am doing mistaken right here?

    operate remove_stuff() {
    $phrases = get_terms( array(
        'taxonomy' => 'experts_industries',
        'hide_empty' => false,
    ) );

    foreach($phrases as $time period) {

        $newSlug = str_replace('-expert-witnesses', '' , $term->slug);

        //update_term_meta($term->id, 'slug', $newSlug);

        //update_post_meta($term->id, 'slug', $newSlug); 

        wp_update_term($term->id, 'experts_industries', array( 'slug' => $newSlug ));

        error_log($term->slug);

    }
}
add_action( 'wp_loaded', 'remove_stuff' );
