error: cannot find declaration `FCL` in `f8d6e0586b0a20c7.FCL`

[temt-ceo]

Environment: Emulator

Hi, I am currently developing a blockchain game.

And I am able to read the script from the SmartContract I deployed on the emulator, but when I executed the transaction, below error had occurred on the emulator running terminal and can not get transaction ID.

Was this error unhelpful?

In the console.log, below is outputted even though I did not output console.log.

What this error mean? Thank you.

My project's repository is public, and the source codes can be found here;
https://github.com/temt-ceo/oraga-esports/blob/develop/src/lib/Shooting.svelte

flow.json is inside /flow_blockchain folder and I am launching emulator inside flow_blockchain directory.
And the problem can be reproducible by git clone with develop branch.

And these commands;

npm i
flow emulator
flow project deploy
flow dev-wallet
npm run dev

The game platform operation is quite straightforward for the user experience.

flow version
> Version: v2.2.19

npm -v : 8.19.2
node -v : v20.12.2
Chip: Apple M1
OS: 15.5

[temt-ceo]

This was not happened a half year ago. I was writing a blog on that time, from that, the version of flow-cli was v2.2.3 ( https://qiita.com/flowcadence/items/8cc25249cda37364cac1 ).

So I want to revert the patch version to v2.2.3. But how I can do it on Mac OS?
In https://developers.flow.com/tools/flow-cli/install ,

It is currently not possible to install earlier versions of the Flow CLI with Homebrew.

cannot find declaration FCL in f8d6e0586b0a20c7.FCL

You are trying to import the FCL contract from the address 0xf8d6e0586b0a20c7, but the error says that the FCL contract was not found at the address. This problem is most likely related to the emulator perhaps the usage of the FCL contract requires more setup (see #797).

The flow discord developer help channels will be much more helpful since this repo is meant for cadence language specific issues.

[temt-ceo]

I see. But There was no something like FCL which flow init can install as the core contract.

And there is no FCL word inside my source code. I want to look into the discord, but I can't see it, suddenly kicked outed.

I might implement the codes by directly deploying the contract on the Testnet to achieve my project, so that if this is the Emulator specific issue, I would not write any more here.

[RZhang05]

Here temt-ceo/oraga-esports/blob/develop/flow_blockchain/transactions.js#L1 is where fcl is used. https://github.com/onflow/fcl-dev-wallet might be helpful. I'm not familiar with these things so I would suggest moving this elsewhere.

@temt-ceo you need to install the FCL contract on the emulator according to that error. It's not a core contract, so flow deps discover won't list it. You can find any contract you want on Contract Browser and install it to your project with Dependency Manager. Then you can run flow project deploy to deploy it on emulator.

Dependency Manager docs: https://developers.flow.com/tools/flow-cli/dependency-manager
Contract Browser: https://contractbrowser.com/

@chasefleming
I see. Is install the FCL contract needed on the Testnet environment too? I soon need to install the contract on the Testnet to test the backend, so I just changed the plan to deploy on Testnet a little earlier. If not, it's ok.

[chasefleming]

@temt-ceo Looks like it is: https://contractbrowser.com/A.addd4bee60218d85.FCL

There's a few listed on Contract Browser.

What's your Discord handle @temt-ceo - I'm not sure why you were kicked, but I can add you back.

[temt-ceo]

Thank you. It's COF.ninja(temtceoticketsonchain).
New ESports project creator. URL is already ready -> https://oraga-esports.com/ . Maybe 7/7 is the release day.

Hey @temt-ceo , I just checked and it looks like you were automatically banned because your name contains the term "ticket" 😅 .

One of our community moderators is looking into it, but it might take a day or two. You should also be able to rejoin if you change your username not to include that keyword.

[temt-ceo]

@jribbink Yes, Thanks!
