REST API: Undefined Array Key

[Niijimasama]

I created the API action below: (v2024)

$app->get('/GetEmpInfo[/{uno}]', function ($request, $response, $args) {
        $uno = $args["uno"] ?? null;
        if ($pfno !== null) {
			$sql = "select * from employees where pfno = ".$uno;
            $info = ExecuteRow($sql);            
        }else{
            $info = (0);
        }	
		return $response->withJson($info);
    });

On running via URL: http://localhost/myapp/api/getempinfo/2
it returns a value of zero i.e. it does not pick the 2.
When I put an echo statement to determine the value of $args["uno"] , I get the error undefined array key.

I have no idea what I am missing.
Any help would be highly appreciated.

Make sure you use the same lettercase for the action name ("GetEmpInfo" vs. "getempinfo").

Thanks for the response.
I get the same error i.e. Undefined array key.

UPDATE
I changed some advanced settings and it just worked. Don't know which exact one it it but they are:

1. Unchecked "Use Route Cache".
2. Unchecked "Generate Production config file".
3. Checked "Generate Route Groups".

Will test further to see which what caused it to work.

It should be 1. After changing routes, you need to remove old cache. See Use route cache:
Notes:
1. When enabled, the cache will be compiled once and never be regenerated again.
2. When you deploy new versions of your scripts (for example, after adding or deleting a table) to production, you must delete the generated file (<ProjectFolder>/<LogFolder>/cache/RouteCache.php) to ensure that the cache will be re-compiled.
