Statemine blocks 5753828, 5753849 can not be decoded

@wliyongfeng we found a workaround which uses typesBundle overrides. This snippet is for rococo but it works the same way for Kusama Asset Hub by adjusting runtime versions and specName

import { OverrideBundleDefinition } from "@polkadot/types/types";

const definitions: OverrideBundleDefinition = {
  types: [
    {
      minmax: [0, 10004],
      types: {
        NovaAssetId: "Option<AssetId>"
      },
    },
    {
      minmax: [10005, null],
      types: {
        NovaAssetId: "Option<MultiLocation>"
      },
    },
  ],
  signedExtensions: {
    ChargeAssetTxPayment: {
      extrinsic: {
        tip: 'Compact<Balance>',
        // eslint-disable-next-line sort-keys
        assetId: 'NovaAssetId'
      },
      payload: {}
    }
  }
};

export default { typesBundle: { spec: { "statemine": definitions } } };

@valentunn I tried and it works. It's very nice, love you.

@jacogr Could you take a look at this issue and #5734? They are crucial to explorers who depend on polkadot api.

This seems to be related to ChargeAssetTxPayment signed extension being used in transactions. Our guess is that API doesn't infer types of signed extensions from runtime metadata correctly. For ChargeAssetTxPayment, its type is a struct with tip and assetId. Type for assetId was changed from u32 to MultiLocation with most recent Kusama/Westmint upgrades
This introduces issues for our indexers as well

@jacogr Could you release a new version of @polkadot/api? So we can update our dependencies.
