Hey @Mikhail,
When that option is set it will try to set all the json data from the binary file and some of those fields might not exist. The snippet below from the docs might help.
If set to active, all JSON data is replaced with the data retrieved from binary key. If it is not set to active, the data will be written to a single key. This field is displayed when 'Binary to JSON' is selected from the Mode dropdown list.
