Trait item implementation is missing: `reserve_withdraw_assets`

Question

I am running the Astar node locally and pointing to the astar-frame repository which is cloned on my local machine. In the Astar node repository, I added the paths-override method to the point all dependencies of astar-frame to the local folder which solved some dependency issues.

When building the Astar node using cargo build --release, I get the following error:

  error[E0046]: not all trait items implemented, missing: `reserve_withdraw_assets`
    --> /Users/snowmead/.cargo/git/checkouts/polkadot-4038f27d5e4ea2e8/c22e1c4/runtime/polkadot/src/weights/pallet_xcm.rs:47:1
     |

     | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ missing `reserve_withdraw_assets` in implementation
     |
     = help: implement the missing item: `fn reserve_withdraw_assets() -> _feps::Weight { todo!() }`

Since I haven't modified anything in astar-frame pallet-xcm, I believe this might be a dependency issue. And to confirm that this trait item is implemented, we see in the pallet_xcm::Config trait that it uses pallet_xcm::weights::SubstrateWeight<Runtime>; which implements the reserve_withdraw_assets trait item.

Answer 1

I applied a temporary fix which was to rename the pallet-xcm dependency to astar-xcm in astar-frame and Astar to avoid dependency conflicts with the pallet-xcm subdependency from polkadot-runtime.
