error[E0277]: the trait bound `[bool; 2]: From<[bool; 3]>` is not satisfied

   | ^^^^^^^^^^^^^^^^^^^^^^^ the trait `From<[bool; 3]>` is not implemented for `[bool; 2]`

   = help: the following other types implement trait `From<T>`:
             <&'a [ascii::ascii_char::AsciiChar] as From<&'a ascii::ascii_str::AsciiStr>>
             <&'a [u32; 4] as From<&'a ppv_lite86::x86_64::vec128_storage>>
             <&'a [u8] as From<&'a ascii::ascii_str::AsciiStr>>
             <&'a mut [ascii::ascii_char::AsciiChar] as From<&'a mut ascii::ascii_str::AsciiStr>>
             <[T; LANES] as From<Simd<T, LANES>>>
             <[bool; LANES] as From<Mask<T, LANES>>>
             <[u128; 1] as From<ppv_lite86::x86_64::vec128_storage>>
             <[u128; 2] as From<ppv_lite86::x86_64::vec256_storage>>
           and 7 others
   = note: required because of the requirements on the impl of `Into<[bool; 2]>` for `[bool; 3]`
   = note: this error originates in the attribute macro `graphql_subscription` (in Nightly builds, run with -Z macro-backtrace for more info)
