Unable to create Enum via index #180

Closed frankli-dev closed 2 years ago

frankli-dev commented 3 years ago

The querying through the substrate frontend template interactor fails with the following error.

Unhandled Rejection (Error): createType(Vec<StorageKey>):: createType(CurrencyId):: Unable to create Enum via index 203, in dot, token

I added the additional types as the following

"CurrencyId": {
    "_enum": {
      "DOT": null,
      "TOKEN": "H160"
    }
  },

The query works well if I use the polkadotjs app with the provided additional types. Is this because the frontend template still uses the @polkadot ^3.9.3 ?

Does substrate-front-end-template support for enum types on the UI? sth like as a dropdown of enum options?

The CurrencyId is defined as enum. But on the interactor, not sure how to specify it. image

Using polkadotjs/api, how can I call the query with the enum parameter?

const transformed = ["xxxx", "token(0xcb82e435e4665fda7cc0e6ced374085d850f23a8)"];
    await api.query.tokens.accounts(...transformed, result => {
      console.log(result)
    });

This is the error when I am getting when running the latest substrate-front-end, with the latest substrate-node-template.

Same here, have you found a solution?

This problem was resolved for me when I updated "caniuse-lite@npm:^1.0.0," npm package.

The exact details for the package that fixed the issue are listed below. (copied from yarn.lock)

version: 1.0.30001274 resolution: "caniuse-lite@npm:1.0.30001274" checksum: 75790d021edbc68dbb36c0bc63255fad1e7aa3986039e685d10340e7e9a37147b0ddedaba22cf6c52b3657cca794ed41af88045ad5cce79084e9361e95f1c5d4

Custom types are no longer needed and is made known to polkadot-js api via metadata. So this issue is no longer relevant.
