Upload Delegation - Error: stored principal and passed principal must match

[rinaldorossiavvale]

We are currently in the process of migrating our code to new version.

Our current focus is on uploading files through delegation. Here are the steps we've taken in the console:

• Log in with the command: w3 login [my-mail]
• Specify the space using: w3 space use did:key:z6Mkf6GqWzVJQVdX5d4S4skrRetFRXPM2YwTarvn7fg2NLZH
• Generate a key with: npx ucan-key ed
• Create a delegation with: w3 delegation create did:key:z6MkjDpk6K6B4Bec2b2M98SESAVz4iquVyfXVSpARSw4LKT1

During the client creation on React:

const principal = Signer.parse(process.env.REACT_WEB3_STORAGE_KEY)
const client = await Client.create({ principal })

we have an error in console:

Uncaught (in promise) Error: store cannot be used with did:key:z6MkjDpk6K6B4Bec2b2M98SESAVz4iquVyfXVSpARSw4LKT1, stored principal and passed principal must match

Try using the in-memory store:

import * as Client from '@web3-storage/w3up-client'
import { StoreMemory } from '@web3-storage/w3up-client/stores'

const principal = Signer.parse("...")
const store = new StoreMemory()
const client = await Client.create({ principal, store })

[rinaldorossiavvale]

Try using the in-memory store:

import * as Client from '@web3-storage/w3up-client'
import { StoreMemory } from '@web3-storage/w3up-client/stores'

const principal = Signer.parse("...")
const store = new StoreMemory()
const client = await Client.create({ principal, store })

Thank you, now I'm able to create the client

Please fix you code block changing the import with this:

import { StoreMemory } from '@web3-storage/access/stores/store-memory'

now in parseProof function:

/** @param {string} data Base64 encoded CAR file */
async function parseProof (data) {
  const blocks = []
  const reader = await CarReader.fromBytes(Buffer.from(data, 'base64'))
  for await (const block of reader.blocks()) {
    blocks.push(block)
  }
  return importDAG(blocks)
}

during reader creation I have this error in console:
Uncaught (in promise) Error: Unexpected CID version (28)

Can you please help me? I can't figure out the problem.

@rinaldorossiavvale I didn't have this exact problem but I had a problem with creating the Reader from proof at async decodeReaderComplete. I think my problem was caused because the @web3-storage/w3up-cli package on NPM is over a year out of date (3.0.1) and potentially generated invalid proof data. You might want to try what I did: download the @web3-storage/w3up-cli package straight from GitHub and execute the key/proof creation commands again with the GitHub version (7.2.1). Good luck!

[magror]

@rinaldorossiavvale Also, the code block
import { StoreMemory } from '@web3-storage/w3up-client/stores'
IS correct. You might have an outdated version of @web3-storage/w3up-client if that import didn't work for you.

[magror]

@rinaldorossiavvale Finally, I just realized that it looks like you are passing did:key:z6MkjDpk6K6B4Bec2b2M98SESAVz4iquVyfXVSpARSw4LKT1
as your principal. That value is not a principal key; it is a DID.

When you generate a Key/DID pair, use npx ucan-key ed --json (or w3 key create). You get BOTH a KEY and a DID. You use the Key value for PRINCIPAL, and you give the DID to the w3 delegation create <did_from_ucan-key_command_above> --can 'store/*' --can 'upload/*' | base64 command, which generates the PROOF.

[rinaldorossiavvale]

import { StoreMemory } from '@web3-storage/w3up-client/stores'

@magror I'm already passing the key as principal and I created the proof starting from the did.
I'm not putting the did as principal

[rinaldorossiavvale]

import { StoreMemory } from '@web3-storage/w3up-client/stores'

@magror upgrading to 12.1.0 throw me an error in console

UnhandledSchemeError: Reading from "node:util" is not handled by plugins (Unhandled scheme). Webpack supports "data:" and "file:" URIs by default

[alanshaw]

@rinaldorossiavvale v12.2.1 should fix this, use import:

import { StoreMemory } from '@web3-storage/w3up-client/stores/memory'

[rinaldorossiavvale]

import { StoreMemory } from '@web3-storage/w3up-client/stores/memory'

@alanshaw upgraded to v12.2.1 but on reader creation it throw:

decoder.js:62 Uncaught (in promise) Error: Unexpected CID version (28) at readCid (decoder.js:62:1) at async readBlockHead (decoder.js:76:1) at async readBlock (decoder.js:85:28) at async Object.blocks (decoder.js:113:1) at async decodeReaderComplete (reader-browser.js:53:1)

@rinaldorossiavvale Have you downloaded the new version of the CLI from GitHub and generated a brand new set of key/proof?

@magror

• uninstalled the cli: npm uninstall -g @web3-storage/w3cli
• installed again: npm install -g @web3-storage/w3cli
• re-generate key/proof

and now I have:
Uncaught (in promise) Error: Unexpected CID version (11776) at readCid (decoder.js:62:1) at async readBlockHead (decoder.js:76:1) at async readBlock (decoder.js:85:28) at async Object.blocks (decoder.js:113:1) at async decodeReaderComplete (reader-browser.js:53:1)

[magror]

@rinaldorossiavvale Do not use the version on NPM. It is out of date. I am recommending you go to GitHub and clone the CLI project directly from GitHub. GitHub has version 7.5.0, whereas NPM only has version 3.0.1

• go to https://github.com/web3-storage/w3cli
• clone the repo using the link found in the green "code" button" ( create a new folder for the repo clone, cd into it in your command line, then command: git clone https://github.com/web3-storage/w3cli.git) notice the .git on the end of the url
• once you have cloned the GitHub repo, cd into the downloaded w3cli folder and do npm install to install all the node_modules folder and everything
• Then you can do npm exec w3 login <email> to start regenerating your key/proof combo

[rinaldorossiavvale]

w3 delegation create <did_from_ucan-key_command_above> --can 'store/' --can 'upload/' | base64

@magror done but always the same error.
