mint | Math Interoperability Types

I am facing a relatively tricky situation here that seemed quite easy at first sight. After moving those three members from the parent class Parent to its child class Child it seems that I'm no longer able to take advantage of the default constructor.

Why? And is there a way out here without having to specifically implement a Child(...) constructor. Seems counterintuitive at first... Actually I would have thought that the first example is where it fails (thinking that the Child class' constructor would overshadow the one of its parent).

I have been trying to interact with a contract on the AVAX chain using web3js and it keeps throwing the error, "TypeError: Cannot read properties of undefined (reading 'send')". I cannot figure out why this is happening, as it should be a valid statement. If anyone can help that would be awesome.

Hey guys how y'all doing? I have a question. So I have this website which mints an Avatar picture of user's choice of pieces (background color, nose types, eyes types etc.).

The contract that I am using right now works just fine for the website. However, it is able to mint from snowtrace as well. My question is, I want to limit my contract such that, it should only allow minting from the website.

I want to prevent any others to mint dummy stuff in my contract using contract interaction snowtrace. Contract should only allow minting from the website. If have any suggestions please let me know, thanks.

I've read here that it is possible to mint 2^256 nfts in a single transaction. I've tried to achieve this by directly assigning _owners and _balances mappings but ofc these are private variables so i can't change them. I tried making an _mint() override but that also didn't work. How does this process work?

I get a list of tokens own by a publicKey thanks to that method :

I am facing issue with React application while compilation. Please find the issue below and screenshot.

Shellsheck is a static analysis tool for shell scripts which can be installed local on some Linux systems and can used without installation online for checking bash scripts for some errors.

• https://github.com/koalaman/shellcheck
• https://www.shellcheck.net/
• https://man.archlinux.org/man/shellcheck.1.en

Testing envirement:

• Linux Mint (Ubuntu edition)
• Given are a working bash script which which echo "I a echo from main file" and a source file which echo "I am a echo from source file".
• Booth file are located in same folder.
• tested with shellcheck 0.7.1-1, by local installed version.

main.sh

I created an ERC721 token using openzeppelin like this:

I have cloned this NEAR REST API SERVER repo into my local system and haven't made any changes to its original code. Only added console logs for debugging purpose. Using its API, I have successfully deployed a contract to testnet account and also called that contract.

But when comes to NFT part, its not working. I'm calling /mint_nft API and getting 500 Internal Server Error.

It's breaking here:

let create_token = await token.ViewNFT(tokenId, contract);

create_token is null.

If I do minting with NEAR CLI, its working fine and I can see that NFT in my testnet wallet..

near call $ID nft_mint '{"token_id": "02", "receiver_id": "'$ID'", "token_metadata": { "title": "Design #2", "description": "Art Design", "media": "https://ipfs.io/ipfs/Qme7ss3ARVgxv6rXqVPiikMJ8u2NLgmgszg13pYrDKEoiu", "copies": 1}}' --accountId $ID --deposit 0.1
