Unsupported glossary source and target language pair - DeepL

Unsupported glossary source and target language pair

DeepL API gives you this error because you missed to get the fact glossaries in DeepL are extremely reduced as functionality.

Error text is:

{"message":"Unsupported glossary source and target language pair"}

DeepL API documentation says that only these pairs of languages are supported:

• EN (English)
• DE (German)
• FR (French)
• ES (Spanish)
• JA (Japanese)
• IT (Italian)
• PL (Polish)
• NL (Dutch)

Let's say it clear: Glossary English and other language out of that list is unsupported. DeepL indicates they support 30+ languages but in fact number of languages with full support only 8. All other have limited set of support. 

Other limitations

We dont really know the real reason why DeepL introduces so stupid constraint on their functionality.

But there are other annoying limitations as glossaries cannot be changed. If you need to make a change, you should download it, change it, uploaded it. Because it will have new ID, access to glossary should be done by name.
