Save Posts to local json file (Field \"language\" is not defined by type RootQueryToEventConnectionWhereArgs.)

[ATOMsan]

I'm trying to save my custom post type posts to local json file but the problem is when i save it with the language attribute a received the error.

{"errors":[{"message":"Field "language" is not defined by type RootQueryToEventConnectionWhereArgs.","extensions":{"category":"graphql"},"locations":[{"line":2,"column":44}]}]}

Maybe you help me to fix my code or maybe you can suggest solution to save posts to local json file.

Also in debug when file trying to save post there is one more error
