tested with 2.6.17 - not working

@terales @antfu sorry for tagging you guys
Might have a Setup, issue but I doubt that for now. I would like to debug more, but I don't get the request to the DeepL API logged.
But getting this done is higher in my priority list than my feature request. Just saying, currently this is a blocker, since we have to fall back to the least optimal google translation :/

Hey @OsirisFrik, could you help to take a look at this and see if it's persist on your side? Thanks.

[OsirisFrik]

I checked this and read the documentation, to use a DeepL free api require a free api key, my country is not allowed to contract DeepL, and I don't have any credit card of a allowed country to contract for test, but I can fix it just based in the docs.

[alexanderniebuhr]

@OsirisFrik @antfu I am using a free api key generated for my user, and it does throw the error 400.

@alexanderniebuhr I have make the logger print more information in #641. While I can't not reproduce myself, you can try with the latest version and share the error log? Thanks

EDIT: can it be caused, because we use language identifiers with two parts, e.g. en-GB?

[alexanderniebuhr]

As soon as I change i18n-ally.translate.engines back to google it works.

[antfu]

Not sure, can you try with de -> en?

[alexanderniebuhr]

yeah.. de -> en works.. but de-DE -> en-GB does not work.
Can you split these in code, since we do need to use full identifiers in our projects.
Here the docs what is supported source and target languages: https://www.deepl.com/docs-api/translating-text/request/
Actually it should give back a api response, but that api response from deepl is not logged, maybe caused by an error thrown before logging

[antfu]

Ah ok then. We could strip the second code when passing to deepl then. Thanks for investigating!

[alexanderniebuhr]

always happy to help :)
