I've followed several related solution. But I'm still facing the problem. I've applied the following code for my custom post query by taxonomy (category). But it's not working. I think my problem with 'terms'.

$terms = get_terms('service_cat');
$services_post = new WP_Query(array(
    'post_type'         => 'service',
    'posts_per_page'    => -1,
    'tax_query' => array(
        array(
            'taxonomy' => 'service_cat',
            'field' => 'cat1',
            'terms' => $terms
        )
    ),
));

I also tried by the following code

$services_post = new WP_Query(array(
            'post_type'         => 'service',
            'posts_per_page'    => -1,
            'category_name'     => 'cat1' 
))

Edited to reflect question in OP's comment.

The contents of the tax_query array are not exactly right: as you're querying by slug, the field parameter of the individual taxonomy query should be "slug".

You're currently basically querying for all service posts from all service categories (well, not even that, because get_terms returns objects, but still).

To query for a single (or more than one) specific terms from which to load posts, specify the terms in the terms array. tax_query is then parsed accordingly.

$services_post = new WP_Query( array(
    'post_type'         => 'service',
    'posts_per_page'    => -1,
    'tax_query' => array(
        array(
            'taxonomy' => 'service_cat',
            'field' => 'slug',
            'terms' => array( 'cat1' ) // Array of service categories you wish to retrieve posts from
        )
    )
) );

By the way, I am assuming you want to retrieve all posts of post type service
