Data to be sent:

{
    "data": {
        "name": "heuristic Ratione quaerat consectetur magnam fugiat placeat",
        "description": "<p>- Guarantee the product as in the real picture</p><p>- All products are the same as in the pictures.</p><p>- Guarantee that you won't be disappointed</p><p>- The product is made of good quality materials, meticulously sewn.</p><p>- Flexible balance with our feet.</p><p>- Products manufactured according to international standards, using grade A materials, are durable, not easily broken</p><p>- Goes with every outfit, every occasion.</p>",
        "variants": [
            {
                "id": 67,
                "price": 300,
                "unit": "1 gram",
                "stock": 999
            }
        ]
    },
    "target": "th",
    "source": "en"
}

With this dataset, the library goes into an infinite loop with the following error:

How do I solve it? Thank you

Solved. Don't need to convert data that is fed to JSON. Thank you. :D
