wordpress.org – Bootstrap is not named in my WordPress theme

An error persists when I look at my bootstrap.min.css file in the page resource, which gives me the message "Failed to load the resource: the server responded with a status of 404 (Not Found)" = = http: // theasianbean.local / wp-content / themes / test-theme / bootstrap / css / bootstrap.min.css.map

However, the bootstrap appears in the browser, so it should go, right?
I am fairly new to this field and I do not understand why I am getting this error. Yet my theme shows the bootstrap.

I have this code:

function theme_add_bootstrap () {
wp_enqueue_style (& # 39; bootstrap-css & # 39 ;, get_template_directory_uri (). & # 39; /bootstrap/css/bootstrap.min.css');
wp_enqueue_style (style-css & nbsp ;, get_template_directory_uri (). & # 39; /style.css');
wp_enqueue_script (bootstrap-js, get_template_directory_uri (). bootstrap / js / bootstrap.min.js, array (), 3.0.0, true );
}

add_action (& # 39; wp_enqueue_scripts & # 39 ;, theme_add_bootstrap & # 39;);

In my test theme folder, I have a folder named "bootstrap" in which I have my CSS and JS boot files.
