Error after “instantiateWithCode queued” when deploying via use.ink UI

[AbdulrahmanFiala]

Hi everyone — I’m following the “Deploy your contract” guide on ink! v6: https://use.ink/docs/v6/

However, when I attempt to instantiate a contract via the UI at https://ui.use.ink/ the following happens:

I click “Upload & Instantiate” and the UI shows status: instantiateWithCode queued

Then it errors out (see image attached) instead of completing the deployment.

I’m not sure what the root cause is — whether it’s the node, the compiled contract, metadata mismatch, or something else.

I haven't been able to replicate it might be related to #578, to confirm can you open the console and see if there is this error:

index-Bcx2wWl-.js:56 Error: The WASM interface has not been initialized. Ensure that you wait for the initialization Promise with waitReady() from [@polkadot](https://t.me/polkadot)/wasm-crypto (or cryptoWaitReady() from [@polkadot](https://t.me/polkadot)/util-crypto) before attempting to use WASM-only interfaces.

Yes, indeed, this is the error that appears at the console. How should I be able to resolve this error?

I got the same deploying issue, but without any error in the console.
I am using ink! node version 0.47.0 and ink! v6.
