Data array does not react on change

Hi, I have a data.uploadErrors array which contains messages from upload validation. The problem is that I can not clear this array and fill it with new values. Previous items remain in array. Can not remove it.
Thisi s really insane cause it look like a bug in Vue2 if project became huge. This is not a first time I face that data does not react on change. PLEASE look at the issue on Stackoverflow.

It drives me crazy cause it is pretty simple usecase. Did anybody hear about it in Vue2? Thanks a lot.

This issue has been caused by missing option in Buefy upload component named “native”.
