Missing IPLD format "dag-jose"

[olnrt]

Hello,

By following the README code, and this tutorial, I am faced with the dag-jose codec missing error.

import Ipfs from 'ipfs-core'
import dagJose from 'dag-jose'
import { convert } from 'blockcodec-to-ipld-format'
import { DID } from 'dids'
import { Ed25519Provider } from 'key-did-provider-ed25519'
import KeyResolver from 'key-did-resolver'

const dagJoseFormat = convert(dagJose)
ipfs = await Ipfs.create({ ipld: { formats: [dagJoseFormat] } })

const seed = fromString(SEED, 'base16')
const provider = new Ed25519Provider(seed)
const  did = new DID({ provider, resolver: KeyResolver.default.getResolver() })
await did.authenticate()

const { jws, linkedBlock } = await did.createDagJWS('test')
const jwsCid = await ipfs.dag.put(jws, { format: 'dag-jose', hashAlg: 'sha2-256' })

the dagJoseFormat looks like :

{
  codec: undefined,
  defaultHashAlg: 18,
  util: {
    serialize: [Function: serialize],
    deserialize: [Function: deserialize],
    cid: [AsyncFunction: cid]
  },
  resolver: { resolve: [Function (anonymous)], tree: [GeneratorFunction: tree] }
}

(I am surprised the dagJoseFormat.codec is undefined, and I've tried to 'force' it to 'dag-jose' with no success)

This throws the error :

Error: Missing IPLD format "dag-jose"
    at IPLDResolver.loadFormat (/dids/node_modules/ipfs-core/src/runtime/ipld.js:46:17)

With the following libs

    "blockcodec-to-ipld-format": "^1.0.0",
    "dag-jose": "^0.3.0",
    "dids": "^2.1.0",
    "ipfs-core": "^0.6.1",
    "key-did-provider-ed25519": "^1.1.0",
    "key-did-resolver": "^1.2.0",
    "uint8arrays": "^2.1.5"

I've found other issues telling this may happen, but with older dependencies, and I am surprised it can happen again with the ceramic blog tutorial and up to date code.

Last thing, I wonder why ipfs is directly used with dag+block, whereas I thought ceramic was the storage used with js-did. Is it possible to sign and encrypt documents directly in ceramic or is it planed ?
thanks.

this issue can be closed, as it is similar to ceramicnetwork/js-ceramic#1429 (comment)
Here, the import dagJose from 'dag-jose' embeds it in a default member. It implies to use const dagJoseFormat = convert(dagJose.default) to make everything work.
