can't use array in languages configuration

[maguzzi]

Hi,
If I try to put an array in the language config (_config.yml), hexo generate fails with this error:

language: [en,es]

TypeError: lang.toLowerCase is not a function
    at toMomentLocale (D:\marcoaguzzi_src\node_modules\hexo-theme-icarus\node_modules\hexo\lib\plugins\helper\date.js:87:15)

hexo: 7.0.0
node: 20.10.0

hexo icarus theme is at lastest version
am I missing something?

thanks!

I've tried some debugging, and the error is only non non-post pages (index, tags... so the input causing an error is the languages being an array).
I've tried a fix, stating:
if lang.length>1 => lang=lang[0]
doing so the error is prevented, but the message with the create, update, and read time gets wrong, such as:

4 minutos de lectura => 4 mintues de lectura (times are in english)

@maguzzi This should be fixed with 49568ab. However, Icarus currently cannot really take advantage of multiple languages set in _config.yml.

Thanks for the answer! I don't know the nodejs ecosystem and didn't really understand yet how to use a custom version of the icarus theme (or of a plugin) without referencing the one in the node_modules folder. Do you have any pointers I can follow, so that I can expertiment a little bit?
Thanks
