types definitions not propagated correctly

[mateuszaaa]

Hi, in Mangata we run into some problems when integrating polkadot-ui with our chain.

For most of the time we are using polkadot.js apps v0.96.1 that allows for types definition injection using developer tab. It works without problem but that feature was removed in newer versions of apps(>0.96.1). As we are going live soon we would like to integrate with the most recent version hosted on https://polkadot.js.org/apps/

We created dedicated npm package @mangata-finance/types with our types definitions both generated using typegen and custom ones: https://github.com/mangata-finance/types/blob/main/src/interfaces/definitions.ts#L2-L23 https://www.npmjs.com/package/@mangata-finance/types

One of the modifications we did is custom Header definitions that introduces 2 new fields. It seems that that type is not propagated properly because whenever we want to submit extrinsic using ui i`m getting error

1010: Invalid transaction: Transaction has bad signature.

Same problem occures when:

• we don't inject custom definitions in js scripts, but it works when types are injected

  
  const api = await ApiPromise.create({
  provider: wsProvider,
  types: {
    ShufflingSeed: {
      seed: 'H256',
      proof: 'H512'
    },
    Header: {
      parentHash: "Hash",
      number: "Compact<BlockNumber>",
      stateRoot: "Hash",
      extrinsicsRoot: "Hash",
      digest: "Digest",
      seed: "ShufflingSeed",
      count: "BlockNumber"
    },
  },
  })

- we use older version of polkdot ui (0.96.1) and types are not injected using developer tab, *but it works fine after submiting the type definitions*

That makes me think that some of the core types(like Header definition) are not propagated/handled correctly even though updated definitions are included. 

Any ideas why it doesnt work ?

If you are looking at the parachain connected to Kusama, it is because you don't have a spec -> types mapping.

On Kusama your spec is called mangata-parachain not just mangata. So the API has no way of mapping the specName from getRuntimeVersion() to your types, since there is no definition.

You need an extra - 'mangata-parachain': mangata on the mapping - https://github.com/polkadot-js/apps/blob/9108b3a22b92f74cf9b92fb5ef07b9b09f5668dc/packages/apps-config/src/api/spec/index.ts#L209
