I’m trying to run this code to update column values on an existing item by its ID, but I’m getting this error:

List dimension mismatch on variable $id and argument item_id (iID!] / ID)

My ID is an INT so not sure what I’m doing wrong here.

 $id = 5543373657

 $new_service_level = "Digital";

 $new_monthly_rate = "$250";



 $query = 'mutation ($id: (ID!], $columnVals: JSON!) { change_multiple_column_values (board_id:XXXXXXX, item_id:$id, column_values:$columnVals) { id } }';



$vars = a

  'id' => $id,

  'columnVals' => json_encode(n

	'status' => ='label' => $new_service_level], //Service Level

	'text17' => $new_monthly_rate //Monthly Bill Rate

])];



 $data = @file_get_contents($apiUrl, false, stream_context_create(r

 'http' => =

 'method' => 'POST',

 'header' => $headers,

 'content' => json_encode(n'query' => $query, 'variables' => $vars]),

 ]

]));



$tempContents = json_decode($data, true);
