This is caused by the source language you selected not being supported by DeepL (or its language code not matching what the DeepL API expects). DeepL supports only a limited set of languages; when source_lang is passed as an unsupported code, it returns Value for 'source_lang' not supported. Note that this error comes from the DeepL channel self-test window, not from the translation task itself.

Handling steps:

  1. In the translation channel settings, confirm that the Source Language you selected is one that DeepL actually supports (common ones: EN, ZH, JA, KO, DE, FR, ES, PT, IT, RU, NL, PL, etc.). If you selected Auto Detect or a rare language (such as Thai, Vietnamese, Arabic, Hindi, and so on), DeepL will reject the request.
  2. If the video is in a rare language, do not use DeepL: change the translation channel to an AI channel (DeepSeek / OpenAI ChatGPT / Gemini) and select the correct source language and target language.
  3. Make sure the source language and target language are not the same; also check whether the DeepL account type (Free/Pro) matches the API address you entered.
  4. After changing the settings, save and click Test again.

If you have confirmed that the language is supported by DeepL and it still reports this error, provide the latest logs/ log file (the last 30 lines containing the error) for analysis.
