Problem to get a product data with sp-amazon for PHp

I am building a small webapp with PHP and jlevers/selling-partner-api (https://github.com/jlevers/selling-partner-api).
I need to recover the ASIN starting from EAN code.

I have tried this:

$catalogApi = $connector->catalogItems();


try {
    // EAN code of a product
    $ean = '3578830113254';

    $marketplaceId = 'APJ6JRA9NG5V4';
    $includedData = ["summaries", "images", "salesRanks", "productTypes", "identifiers", "variations"];

    //search EAN
    $response = $catalogApi->searchCatalogItems([
        'marketplaceIds' => [$marketplaceId],  
        'identifiersType' => 'EAN',            
        'identifiers' => [$ean],                
        'includedData' => $includedData        
    ]);

    // Visualizza la risposta
    echo "<pre>";
    print_r($response);
    echo "</pre>";

} catch (Exception $e) {
    // Gestisci gli errori
    echo "Errore: ";
    var_dump($e->getMessage());
}

but i receive this strange error:

SellingPartnerApiSellerCatalogItemsV20220401Api::getCatalogItem():
Argument #1 ($asin) must be of type string, array given

    i have try to change the code as you suggest:

        $catalogApi = $connector->catalogItems();

try {
    // EAN code of a product
    $ean = '3578830113254';

    $marketplaceId = 'APJ6JRA9NG5V4';
    $includedData = ["summaries", "images", "salesRanks", "productTypes", "identifiers", "variations"];

    //search EAN
    $response = $catalogApi->searchCatalogItems([
        'marketplaceIds' => [$marketplaceId],  
        'identifiersType' => 'EAN',            
        'identifiers' => $ean,                
        'includedData' => $includedData        
    ]);

    // Visualizza la risposta
    echo "<pre>";
    print_r($response);
    echo "</pre>";

} catch (Exception $e) {
    // Gestisci gli errori
    echo "Errore: ";
    var_dump($e->getMessage());
}

    but now the error is:

    Array to string conversion, ithink that something is wrong in the API

    As per Amazon searchCatalogItem API call, the identifiers parameter is:

    A comma-delimited list of product identifiers to search the Amazon catalog for.

    Hence you will need change your code, in order to set the identifiers as a string (not as an array of strings). In case you need to ask for more than 1 EAN, just set that parameter with a comma-separated list of EAN codes.

    Warning: a maximum of 20 identifiers may be specified in the identifiers parameter.
