Warning: array_intersect_key(): Expected parameter 1 to be an array,…..

Hi there,

I am currently receiving the following error:

Warning: array_intersect_key(): Expected parameter 1 to be an array, string given in /path on line 1402.

Thats the line:

if ( isset( $callback[‘args’] ) ) {
$endpoint_data[‘args’] = array();

foreach ( $callback[‘args’] as $key => $opts ) {
$arg_data = array_intersect_key( $opts, $allowed_schema_keywords );
$arg_data[‘required’] = ! empty( $opts[‘required’] );

$endpoint_data[‘args’][ $key ] = $arg_data;
}
}

Does someone know how to fix?

Br and thanks a lot
David
