Make API call using "auto" language detection leads to an error

[tivaliy]

I have the following issue when trying to make /v2/check API call with language set to auto:

Any suggestion on how that could be fixed?

Hi, do you happen to run this image on an ARM64 architecture? If so, this may be duplicate with #66.

Thanks for the quick response. In that case, I have your issue reproduced and I am working on getting it fixed in #66. I'll mark this one as duplicate. Could you track #66 instead?
