- the read function which returns the Vector of Buyer struct is giving error

```auto
pub struct Buyer {
    pub buyer: Identity,
    pub quantity_bought: u64,
    pub buy_price_per_item: u64,
}

```

```auto
buyers: StorageMap<u64, StorageVec<Buyer>> = StorageMap {},

```

```auto
#[storage(read)]
    fn get_buyers(listing_id: u64) -> Vec<Buyer> {
        let mut buyers = Vec::new();

        if let storage_vec_key = storage.buyers.get(listing_id) {
            let len = storage_vec_key.len();
            let mut i = 0;
            while i < len {
                if let Some(storage_key) = storage_vec_key.get(i) {
                    buyers.push(storage_key.read());

Hey @DevilAsap, can you please update the toolchain to the latest and see if the issue still persists? please make sure the forc version is `0.64.0` and fuel-core `0.36.0`

Interesting.

Our issue I think stems from the following contract change. We’re basically just trying to be able to return a Configurable Constant as we could not find any definition if that is possible or not. @naz3eh could you enlighten me?

Basically this is the change:

```auto
#[storage(read)]
    fn max_supply() -> Option<u64> {
        Some(MAX_SUPPLY)
    }

```

Max supply itself is defined like so:

```auto
MAX_SUPPLY: u64 = 3,

```
