Get an E_UNKNOWN error from purchaseErrorListener callback

[5JJ]

Hi.
Sometimes I get an E_UNKNOWN error when failed to purchase an item in production
It occurs both in android and ios with response code below.

I can't reproduce this error in dev environment.
I want to know the reason and solution if possible. 🥲

• android
  {
  code: E_UNKNOWN
  debugMessage: An internal error occurred.
  message: An unknown or unexpected error has occurred. Please try again later.
  responseCode: 6
  }

• ios
  {
  code: E_UNKNOWN
  debugMessage: Couldn’t communicate with a helper application.
  message: Couldn’t communicate with a helper application.
  responseCode: 4097
  }
