Error tranfering NFT from Ethereum Goerli to Polygon Edge: proposal execution is skipped about chainbridge HOT 3 CLOSED

Hey @pedro-haeser-cryptotao! It looks like vote transaction (0x3589d3ab8183d414aa4230ca14984e44c9fd953991500bb2b837337a9ea71f7d) somehow failed on blockchain, there could be dozens of reasons, so first of all, you should find logs of this transaction to understand why

from chainbridge.

Hi @P1sar , thanks for the clarifications. I tried the other way around -- bridging a NFT from Polygon Edge to Goerli in order to get logs easier from Etherscan.

It seems that during the proposal execution the transaction was reverted due to "Fail with error 'ERC721: operator query for nonexistent token'"

Just to ensure that I didn't do something fundamentally wrong during my steps...

1. I added a minter role to the handler contract on Polygon Edge blockchain
2. Minted token "0x54"
3. Checked the owner of token 0x54: it was assigned to the Polygon Edge chainbridge admin account
4. Approved the transfer from token 0x54 from ERC 721 contract to ERC 721 contract handler (both contracts on Polygon Edge)
5. Called deposit method for token 0x54 setting the recipient as the Goerli ERC 721 contract address

These are the logs from last step:

And looking at Etherscan the proposal was successfully submitted, however the execution failed with the error above

Just wanted to check if you see anything wrong with the steps above while I keep troubleshooting it.
The reason why I ask that is because I am trying to transfer the NFT from Polygon Edge to Goerli... so I kinda of expected that the token shouldn't exist at Goerli that moment.

Thanks in advance!

You were trying to bridge ERC721 token that was not minted in advance.
If you want bridge to mint the token you need to set Mintable/Burnable param for this token and also grant Bridge as minter roles for your ERC721
