How to use germ_terms() with meta_query for ACF Taxonomy field?

Answer – the correct formulation is…

'meta_query' => array(
array(
'key' => 'Topic',
'value' => "12057",
'compare' => 'LIKE'
)
)

In full:

` $args = array(
‘taxonomy’ => ‘event’,
// ‘order’ => ‘ASC’,
‘hide_empty’ => false,
‘hierarchical’ => true,
// ‘parent’ => 0,

  'meta_query' => array(
    array(
      'key'     => 'Topic',
      'value'   => "12057",
      'compare' => 'LIKE'
    )
  )


);

$events = get_terms( $args );`

Specifically, it seems 'compare' => 'LIKE' needs to be present.

Initially, I had thought the solution was to use double quotes on the value, which I inferred from @hube2’s response to another question.

But actually it works with single or double. The clincher is the present of 'compare' => 'LIKE'.
