Can't run bonding smart contract

Sway
1

Hello guys!

We have tried to implement a bonding smart contract with pretty simple logic buying a token with a discount and unlocking it when time is right.

Here is a link to the code - link

It fails with different errors that are commented on in the code. Please help us to get rid of those once and run it.

  1. Compiler error: thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', sway-ir/src/optimize/dce.rs:93:60 // note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

  2. Error: No method named "len" found for type "StorageKey<StorageVec<Vesting>>".

  3. Error: No method named "push" found for type "StorageKey<StorageVec<Vesting>>".

I also assume that the problem can relate to current beta3 version problems. Here is my toolchain:

Default host: aarch64-apple-darwin
