POST REST API Magento 2

[vincenzondb]

Hi all, I used the service REST API to insert products, but it happens to me a strange thing, when I insert in the title the word "HP 250 G4" I get this error

"object (stdClass) # 289 (1) {[" message "] = > string (22) "Unable to save product"} "

Here's an example of my call to the bees:

$data = array(
                    "product" => array(
                    "sku" => $prod->sku,
                    "name" => 'HP 250 G4',
                    "attributeSetId" => 91,
                    "price" => $prod->price,
                    "status" => 1,
                    "extensionAttributes" => array(
                        "stockItem" => array(
                            "qty" => $prod->qty,
                            "is_in_stock" => true,
                        ),
                    ),
                    "customAttributes" => array(
        array(
            "attributeCode" => "snumero_di_threads_del_process",
            "value" => "valoreTest"
            ),
        array(
            "attributeCode" => "activity",
            "value" => 0
            ),
        array(
            "attributeCode" => "color",
            "value" => 0
            ),
        array(
            "attributeCode" => "category_ids",
            "value" => 241
            ),
        array(
            "attributeCode" => "description",
            "value" => "<p>Test descrizione</p>"
            ),
        array(
            "attributeCode" => "tax_class_id",
            "value" => "2",
            ),
        array(
            "attributeCode" => "short_description",
            "value" => "Descrizione corta",
            ),
        array(
            "attributeCode" => "manufacturer",
            "value" => "Enzo",
            ),
    ),
));  

The strange thing is that if I put in the title of this "HP250 G4" text works. Apparently, it seems that annoys the number separated from other words in the title.

What could be your problem?

Thanks

I found the problem, undergoing various tests, he had created the link rewrite db, and so it was in conflict. The worst thing is that thus special magento I did not specify where the error had occurred.
