CORS Error

[Vindorable]

Hi! I'm trying to use GetBalance/Airdrop for the ArConnect wallet and I'm encountering this issue:

I'm on Testnet (www.arweave.run) and I've also set it in 'ArConnect > Settings > Gateway > select Gateway'.

Access to fetch at 'https://www.arweave.run/mint/Zb8ECPwUAHR3il2iuTd-60aDdCBcw9oQ_FNTJCxQEjg/100000000000000' from origin 'http://localhost:5173' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I'm not sure what to do. Please help.

Thank you for use my repository but I don’t maintenance any more...

I suppose you have 2 problems. Please ask that in Discord of Arweave.

1. www.arweave.run doesn’t work, I think.
2. CORS error is a security function of browser. I think my repository is too old so, you should update npm packages to latest .

If you want to use NFTs on Solana, I recommend to use Metaplex.
Do you know Irys (former name: Bundlr Network)?
Irys is like a storage aggregator using Arweave and support multi chain.
Metaplex use that so, we don’t need to use directly the Arweave anymore.

I made a lot of example script(NFT/Compressed NFT) of Metaplx. Look at this if you're interested in that.

Or check GameShift. NFT minting fee is free for now.
