Upload image API REST

hello, I have installed a clean version of wordpress and added woocommerce.
From an ERP I add the products, categories via API REST, all this without problem.
But when I try to add the images I find several errors that took weeks without finding a solution.
If I try to add the images when I update the product according to the woocommerce documentation (https://woocommerce.github.io/woocommerce-rest-api-docs/#create-a-product) I receive the error 400. I check the json file that sending via API REST and has the same structure indicated in the documentation. Example
{
  “name”: “Bicycle bh 95b”,
  “slug”: “BICYCLE HB”,
  “description”: “Biciclet hb dedicated to road.”,
  “short_description”: “Bicycle bh 95b”,
  “sku”: “70068”,
  “regular_price”: “525”,
  “sale_price”: “”,
  “external_url”: “”,
  “button_text”: “”,
  “tax_class”: “”,
  “manage_stock”: “false”,
  “stock_quantity”: “22”,
  “stock_status”: “instock”,
  “weight”: “0”,
  “shipping_class”: “”,
  “average_rating”: “0.00”,
  “rating_count”: “0”,
  “parent_id”: “0”,
  “purchase_note”: “”,
  “categories”: [
    {
      “id”: “17”
    }
  ],
  “images”: [
    {
      “src”: “https: // <www.myweb.es> /html/wp-content/uploads/2019/04/70068_P1.jpg”
    }
  ]
}
With this json I receive error 400.

I also tried to do it via endpoint media “/ wp-json / wp / v2 / media” to insert the image in the media library first and in this case I receive the unauthorized 401 error. The user with whom I am connecting the API is an administrator. The json sent it with the image in binary. The user has passed it as a parameter or adding to the header and I receive the same error.
I do not know how to upload images, to see if you can give me a solution.

Thank you.
