RGB21 example does not display assetOwner & error when transfering this asset

[rkedez]

assetOwner not displayed

• When I cargo run --example rgb21 with examples/rgb21.rs modified by adding my own outpoint under beneficiary and setting testnet to true in verified_contract .validate call, the stdout only shows (naming=(ticker=("TEST"), name=("Test uda"), details=~), precision=0) at the end of the output where I would also expect the owner to be displayed as is the case with the RGB20 example.

• When importing this contract and rgb state <contract_id> RGB21 the full output is this:

  Global:
  spec := (naming=(ticker=("TEST"), name=("Test uda"), details=~), precision=0)
  created := (1700145223)
  terms := ("")
  tokens := (index=(2), ticker=~, name=~, details=~, preview=1((type=(type=("text"), subtype=~, charset=~), data=0x0000)), media=~, attachments={}, reserves=~)
  
  Owned:
  assetOwner:

• The assetOwner is also not shown with the provided examples/rgb21-simplest.contract.rgb running rgb state
• As an aside, there is an Error: unsupported value `2` for enum `ContainerVer` encountered during decode operation when rgb import a contract created after the recent changes (after commit 943c65d). I assume due to rgb-contracts not yet being updated to contract version 2.

rgb transfer error

• I am not sure this is correlated to the above issue.
• After importing the example RGB21 contract, creating an invoice and a psbt file, rgb transfer shows Error: state provided via PSBT inputs is not sufficient to cover invoice state requirements.

• full logs in which I used rgb aliases for different data directories:
