meta_query needs to be a nested array

either

'meta_query' => array(
  array(
    'key' => 'program_id',
    'value' => '5317',
    'compare' => 'LIKE'
  )
),

or

'meta_query' => [
  [
    'key' => 'program_id',
    'value' => '5317',
    'compare' => 'LIKE'
  ]
],

@trisham the second way is a shorthand that was added in PHP 5.4, similar to how arrays can be declared in JavaScript, which I prefer not to use. Mostly because my IDE does not understand it and shows a syntax error that prevents me from seeing real syntax errors. Besides, it only saves typing out “array” which I do instinctively and would save me what? Less than a second? I also find it a lot less clear when reviewing code.
