import entity from wikidata errors: wikibaseintegrator.wbi_exceptions.MWApiError: 'The supplied language code was not recognized.'

[traopia]

Hi! I have this error for several entities that I am trying to import from wikidata:

wikibaseintegrator.wbi_exceptions.MWApiError: 'The supplied language code was not recognized.'

Or the following error:

wikibaseintegrator.wbi_exceptions.ModificationFailed: 'Label and and description for language code ta can not have the same value.'

How can I deal with this? They are quite a common errors (at least in my experience so far) so I guess there must be a way around. Thank you!
