Tafsir in English Language does not appear while fetching the data from the API by verse or by chapter

[FaizaQamar]

I have tried multiple end points to fetch the tafsir of individual verses and chapters as well in the English Language. But it does not return it in the response. Sample end point used to make request is mentioned below.

Endpoint: https://api.quran.com/api/v4/verses/by_chapter/1?tafsirs=168 Response: { "verses": [ { "id": 1, "verse_number": 1, "verse_key": "1:1", "hizb_number": 1, "rub_el_hizb_number": 1, "ruku_number": 1, "manzil_number": 1, "sajdah_number": null, "page_number": 1, "juz_number": 1 }, { "id": 2, "verse_number": 2, "verse_key": "1:2", "hizb_number": 1, "rub_el_hizb_number": 1, "ruku_number": 1, "manzil_number": 1, "sajdah_number": null, "page_number": 1, "juz_number": 1 }, { "id": 3, "verse_number": 3, "verse_key": "1:3", "hizb_number": 1, "rub_el_hizb_number": 1, "ruku_number": 1, "manzil_number": 1, "sajdah_number": null, "page_number": 1, "juz_number": 1 }, { "id": 4, "verse_number": 4, "verse_key": "1:4", "hizb_number": 1, "rub_el_hizb_number": 1, "ruku_number": 1, "manzil_number": 1, "sajdah_number": null, "page_number": 1, "juz_number": 1 }, { "id": 5, "verse_number": 5, "verse_key": "1:5", "hizb_number": 1, "rub_el_hizb_number": 1, "ruku_number": 1, "manzil_number": 1, "sajdah_number": null, "page_number": 1, "juz_number": 1 }, { "id": 6, "verse_number": 6, "verse_key": "1:6", "hizb_number": 1, "rub_el_hizb_number": 1, "ruku_number": 1, "manzil_number": 1, "sajdah_number": null, "page_number": 1, "juz_number": 1 }, { "id": 7, "verse_number": 7, "verse_key": "1:7", "hizb_number": 1, "rub_el_hizb_number": 1, "ruku_number": 1, "manzil_number": 1, "sajdah_number": null, "page_number": 1, "juz_number": 1 } ], "pagination": { "per_page": 10, "current_page": 1, "next_page": null, "total_pages": 1, "total_records": 7 } }

Other end point: https://api.quran.com/api/v4/verses/by_key/2:5?language=en&words=false&tafsirs=168

But if I use any other language for tafsir e.g. 166 - Bengali, It returns the tafsir. Please look into it.
