I getting error: The transaction execution will likely fail. Do you want to force sending?

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Internal JSON-RPC error. { "code": 3, "message": "execution reverted: ERC721: operator query for nonexistent token", "data": "0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000002c4552433732313a206f70657261746f7220717565727920666f72206e6f6e6578697374656e7420746f6b656e0000000000000000000000000000000000000000" }

How can I solve it?

Hi, welcome! :wave:

I think just like the error message said: operator query for nonexistent token
So you should check the parameter.

Anything wrong?

It seems like you are trying to transfer a ERC721 token, right?

Yes exactly. You are right.

Yes exactly. You are right.

It seems like you deployed the contract, and set admin address, so when did you mint a ERC721 token, I did not find transaction

Can you send me proper document for deploy ERC721 and execute functions.

Maybe you can have a look at this tutorial: Create an NFT and deploy to a public testnet, using Remix

Only for test!!!

I am unable to do it. Can you pleas help me what exact issue arising.

Emmmm, maybe you can share your code at here if possible.

Code is error free because developer deploy it and worked fine. But now when I m trying its not working.
Can I share my anydesk id?

So maybe you can just ask him how to do it.

Not able to contact with him that is why I am trying to fix it from any other person.

Emmm, I do not have source code, so I can not do nothing.
But generally speaking, there should a mint function to generate a new ERC721 token., and then you can transfer it

It seems like you should call createFix() or createAuction() to mint a new ERC721 token, and caller will have a new ERC721 token. And it seems like you are trying to call transferFrom(), in your case, you should use creator account to call token.approve(Another_Account, Token_Id) at first, and then use Another_Account account to call transferFrom(Creator_Address, Another_Account, Token_Id), then you can transfer token successfully.
