Problem with alignment information.

[skharenko-DS]

I have next code:

def translate(
        from_lang: str,
        to_lang: str,
        texts: List[str],
        include_alignment: bool = True
    ) -> List[JSONType]:
        constructed_url = "https://api.cognitive.microsofttranslator.com/translate"
        params = {
            "api-version": "3.0",
            "from": from_lang,
            "to": to_lang,
            "includeAlignment": include_alignment,
            "includeSentenceLength": True,
        }
        headers = {
            "Ocp-Apim-Subscription-Key": "*******",
            "Ocp-Apim-Subscription-Region": "GLOBAL",
            "Content-type": "application/json",
            "X-ClientTraceId": str(uuid.uuid4()),
        }
        body = [{"text": text} for text in texts]
        request = requests.post(
            constructed_url, params=params, headers=headers, json=body
        )
        resp = request.json()
        return resp
result = translate("de", "en", ["Artikelnummer des Kunden"])

and i have a result
{'translations': [{'text': "Customer's item number", 'to': 'en', 'alignment': {'proj': '0:12-11:14 0:12-16:21 14:16-0:9'}, 'sentLen': {'srcSentLen': [24], 'transSentLen': [22]}}]}
so if we look at result:
Original: Artikelnummer des Kunden
Translation: Customer's item number
we see that we have no alignment for the original word "Kunden".
