metaplex | application framework for decentralized NFT

Trying to use a specific version of a node module (v0.2.0) in my own project, but one of my dependencies requires v0.1.8 of the same module. No issue, I thought, that dependency will use v0.1.8 in its nested node_modules folder and my app will use v0.2.0 in my project's node_modules folder. I added v0.2.0 as a dependency to my package.json and ran npm install again. However, for some reason my app points to the other dependency's v0.1.8 module (in its nested node_modules) when I ctrl-click it, instead of the expected v0.2.0 module correctly installed in the project's own node_modules folder. Here's the code I'm using to import from the modules (@metaplex/js relies on v0.1.8 of @solana/spl-token, while I need to use v0.2.0 of @solana/spl-token in my own app):

So I know that compared to most more decentralized blockchains that Solana is fast.

Still, the question I have is whether I should implement my transactions asynchronously off of a queue - so that I can retry failures if something fails etc

This gets further complicated for example if I am using metaplex to create a token with associated metadata etc as it involves 2 transactions: 1 to create the token and another to create the token-metadata for the token

Is there any way to filter a users wallet by metaplex candy machine id?

I know how to get all of a users nfts via getParsedTokenAccountsByOwner.

I am following this tutorial "https://www.youtube.com/watch?v=4LLx7SMAOag&t=446s" and at 9:28 he tells us to input this

I'm trying to complete the upload step to deploy a candy machine and I am using Metaplex v2 and I am using devnet(not using minnet-beta) and "storage": "arweave" also set to devnet but still I get the below output error:

EDIT: Thank you for suggestion actually I have checked my balance it was 0 then added to SOL now it is working well!

I am new to blockchain and i am trying to play with blockchain so I used metaplex and candy-machine to upload and mint dummy nft's which is working fine. The opensource repositories that I am playing with are below:

https://github.com/metaplex-foundation/metaplex https://github.com/exiled-apes/candy-machine-mint

Then for learning purposes, I wanted to divide minting and secondary sales into more than one wallet so I changed JSON and added three test wallets into the creator's array.

Attempting to follow the 'your first request' example here: https://docs.metaplex.com/sdk/js/getting-started#your-first-request

The module referred to in the examples doesn't contain the data needed.

For context, I am using this example to develop the solution explained at step 5 of these instructions: https://gist.github.com/creativedrewy/9bce794ff278aae23b64e6dc8f10e906

Step 1) I install the @metaplex/js package via: yarn add @metaplex/js

Step 2) I import programs from the module by placing import { programs } from '@metaplex/js';.

Step 3) I attempt to unpack Metadata from programs via: const { Metadata } = programs.metadata;

At this stage, if I execute npm run start or yarn run start I see the error that the property Metadata of programs.metadata is undefined. When I look in node_modules/@metaplex/js/ I see that the error is correct.

The only mention of metadata in the module is the function used to lookup metadata once you have the URL. The stage I am at is attempting to retrieve the URL, so this package is not useful, despite being the only one referred to in the docs.

On my MacOs I setup docker container with metaplex (more setup details are in this older separate question) development environment (webpack, react) - and when I change something in code, or not change nothing, randomly (usually after 1-2 min) following error appears:

I have following Dockerfile which I run on my MacBook Air M1 (so inside docker I have linux with M1)
