Error while parsing trained_assistant: missing field language



I have a problem with my assistant. I use snips in (home assistant) I first had a very simple assistant with my own bundle and it worked quite well but was off course very limited. I created a new bundle with the smart lights (and tried others as well) and installed that assistant on my raspberry pi. Now I get the error missing field langue

Error: Unable to read file `"/opt/snips/config/assistant/trained_assistant.json"`
Caused by: missing field `language` at line 1 column 1946 

I looked through the assistant and found a field language_code. When i change it to langue it doesn’t give that error anymore but fails on an other field.

Any idea what’s wrong?
