astarnetwork / api Goto Github PK

this package and its dependencies are very outdated.
Please update the Plasm types, polkadot-js/api version, and remove redundant types that are included in the plasm api by default (e.g., ethereum types).
We also may need to split the type imports into main and Dusty rather than using a single interface folder.

Hi, using shiden network got error when I geting nonce from chain by system_accountNextIndex:
{ code: -32601, message: 'Method not found' },

And this is a common api for polkadot,
https://polkadot.js.org/docs/substrate/rpc/#system

so I want to ask how can I reslove that? Any other JSON RPC api to get nonce?

Simply put, if I try to introduce '@plasm/types' via require, I will get an error.

index.js

require("@plasm/types")

excucte: node index.js:

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /home/...
require() of ES modules is not supported.
require() of /home/... is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.

I tried to use plasm-types libray to run a simple app for transferring tokens between Dusty accounts on plasm. Source code and package.json for running the snippet is found on this git repo

Additionally when i try to do a clear run (delete node_modules and reinstall) i get the same message but with field CheckMortality replaced by CheckNonce. Fields returned by plasm-types library can be found in this file in json format
