BUG: wrong error message on transferring an NFT that doesn't exist (not minted/issued)

[taitruong]

Summary of Bug

I have collection, but this token I transferred doesn't exist. Error returned: not token owner: unauthorized

Environment

• OS: Ubuntu 22.04
• Software version: iris 1.4.1-gon-testnet

Steps to Reproduce

$ iris tx nft-transfer transfer 'nft-transfer' 'channel-22' 'stars183e7ccwsnngj2q8lfxnmekunspnfxs6q8nzqcf' 'arkprotocol002' 'fooBar'            --from iaa183e7ccwsnngj2q8lfxnmekunspnfxs6qxd4v3f            --fees 2000uiris            -b sync --yes --output json
{"height":"0","txhash":"8D7B5329B6339099C7FE012E9B3C4E69B36A381B7E8BD63B8E5B9BE344EEBCD0","codespace":"","code":0,"data":"","raw_log":"[]","logs":[],"info":"","gas_wanted":"0","gas_used":"0","tx":null,"timestamp":"","events":[]}

$ iris query tx 8D7B5329B6339099C7FE012E9B3C4E69B36A381B7E8BD63B8E5B9BE344EEBCD0 --output json | jq
{
  "height": "370014",
  "txhash": "8D7B5329B6339099C7FE012E9B3C4E69B36A381B7E8BD63B8E5B9BE344EEBCD0",
  "codespace": "sdk",
  "code": 4,
  "data": "",
  "raw_log": "failed to execute message; message index: 0: not token owner: unauthorized",

Expected and Actual Behavior

A better error message like token fooBar does not exist!

I believe this is a minor improvement, but not a bug.

I believe this is a minor improvement, but not a bug.

Also here from a functional/business point of view I'd say this is a bug :). It tells user, NFT exists and user is unauthorized to do interchain transfer. But this is not correct, since it doesn't even exist.

This problem has been fixed is nft-transfer#11.
