Error when creating product with webservice

[angel_dope]

Hi everyone, I'm trying to create a product using the webservice but I'm getting always the same error: 

Any idea how I can solve this?

I'm running Prestashop 1.7.6.5

By the way, this is the code snippet i found in product.php, line 6827 is the one starting with foreach
 

    public function modifierWsLinkRewrite()
    {
        foreach ($this->name as $id_lang => $name) {
            if (empty($this->link_rewrite[$id_lang])) {
                $this->link_rewrite[$id_lang] = Tools::link_rewrite($name);
            } elseif (!Validate::isLinkRewrite($this->link_rewrite[$id_lang])) {
                $this->link_rewrite[$id_lang] = Tools::link_rewrite($this->link_rewrite[$id_lang]);
            }
        }

        return true;
    }

Did you managed to find a solution? I'm receiving the same warning and the code is not warning, until I enable the debug mode. With debug mode activated it's working properly.

I also tried to add a breakpoint in this function, but I can't get there.

Thanks!

Hi Alex, I finally made it posting the information straight to the different tables in the database. If you want to do it, you need to use the following tables:

- ps_product
- ps_product_lang
- ps_product_shop
- ps_category_product
- ps_image*
- ps_image_shop

 

*Once created a new line on ps_image, you have to retrieve the id_image field to create the image folders structure for the image, i.e., if the id_image is 749, the folder structure will be [root_folder]\img\p\7\4\9\ and you have to upload the different images to this last folder.  I leave you the html form and the php code I use to upload the image file, create the folder structure and resize the image to the different sizes you need for the store. The php file should be on your stores root folder, and you have to upload a square image to prevent loosing information, because the resize function crops the image. With this code you just have to upload one image and it generates copies in the different size the store uses. 

<form action="https://yourstore.com/upload_image.php" method="post" enctype="multipart/form-data" name="form1">
	<input name="userfile[]" type="file" id="userfile[]" required>
    <input name="id" type="hidden" id="id" value="<%=request.querystring("id")%>">
    <input type="submit" name="button" id="button" value="Enviar">
</form>
