Triggered a test run here: https://github.com/eclipse-theia/theia/actions/runs/13048824155/job/36404384953#step:7:146
Now fails with "Too many requests", which should be unrelated to the script itself.
I'll retrigger

[tsmaeder]

Alternatively, we could add a "translate" script to the root package.json.

Getting "Too many requests" again (https://github.com/eclipse-theia/theia/actions/runs/13048824155). I don’t think there’s anything I can do about it. Deepl status looks fine: https://www.deeplstatus.com/
Maybe we’ve hit our limit? I’m not sure what plan or API token we’re using for the translation service.
@msujew Do you know?

@jfaltermeier My API token almost hasn't been used this month. It seems like we're hitting some rate limiting? I'll take a look at it.

@jfaltermeier I pushed a commit to this PR that should resolve the issue. It seems like DeepL has implemented rather strict rate limiting (without saying what it is - the documentation just says to "try again after a delay").

Thanks, with these commits I get: https://github.com/eclipse-theia/theia/actions/runs/13050402257/job/36409193760#step:7:151

[tsmaeder]

The code looks reasonable to me. Does it work with the deepl API, though?

[msujew]

@tsmaeder This fix has resulted in the PR #14796. This seems to work as expected :)
