error[E0277]: the trait bound is not satisfied for Deserialize<'_>` and Serialize<'_>`

Question

Hi I am currently upgrading our runtime to Polkadot 1.0 but when I try to build it get the following errors

error[E0277]: the trait bound `MintingRateInfo: Deserialize<'_>` is not satisfied
     --> /home/aibrayanov/Blockchain/metaverse_network/dev/pallets/estate/src/lib.rs:249:3
      |
  249 |         pub minting_rate_config: MintingRateInfo,
      |         ^^^ the trait `Deserialize<'_>` is not implemented for `MintingRateInfo`

  error[E0277]: the trait bound `MintingRateInfo: Serialize` is not satisfied
      --> /home/aibrayanov/Blockchain/metaverse_network/dev/pallets/estate/src/lib.rs:61:1
       |
  61   | #[frame_support::pallet]
       | ^^^^^^^^^^^^^^^^^^^^^^^^ the trait `Serialize` is not implemented for `MintingRateInfo`

This error occurs despite that both Serialize and Deserialize are enabled for MintingRateInfo type. The code can be found here

Answer 1

The problem came from defining the Serialize and Deserialize features for the types I replaced the macros

#[derive(
    Encode,
    Decode,
    Eq,
    PartialEq,
    Copy,
    Clone,
    RuntimeDebug,
    MaxEncodedLen,
    PartialOrd,
    Ord,
    TypeInfo,
)]
#[cfg_attr(feature = "std", derive(Serialize, Deserialize))]

with

#[derive(
    Encode,
    Decode,
    Eq,
    PartialEq,
    Copy,
    Clone,
    RuntimeDebug,
    MaxEncodedLen,
    PartialOrd,
    Ord,
    TypeInfo,
    Serialize,
    Deserialize,
)]

Also replaced

[features]
std = [
"serde",
 ...
]

with

[features]
 std = [
    "serde/std",
     ...
    ]

Also, enabled the derive and alloc features of serde and the problem was resolved.
