Able to create alexander APIRx but not kusama, substratetest in react-native

[turingpavan]

Can connect and get details for Alexander, hosted by parity and Web3 Foundation

1. wss://poc3-rpc.polkadot.io/
2. wss://alex.unfrastructure.io/public/ws

import { ApiRx, WsProvider, ApiPromise } from '@polkadot/api';
 var provider;
 var api;
        try {
            provider = new WsProvider(rpcServer);
            api = await ApiRx.create(provider).toPromise();
        } catch (error) {
            console.log(error);
   }

But the issue is,
Fails in following Wsproviders with below error

1. Kusama wss://kusama-rpc.polkadot.io/

You are on an ancient version of the API, as per the message it doesn't have Metadata version 7 support, your API only has support up to v5. (Alexander is only on v3)

Update your API, the latest stable 0.91.1 was actually released yesterday. (Since your is . very far behind, also take a look at the CHANGELOG and UPGRADING guides for changes)

[turingpavan]

After upgrading to 0.91.1 Running metro as NODE_OPTIONS=—max_old_space_size=8192 react-native start Stuck at 97.4% Since 1 hour. This time, it’s bad than wasm crypto

[turingpavan]

Upgraded to 0.91.1
It did load.

       const provider = new WsProvider('wss://poc3-rpc.polkadot.io/');
       const  api = await ApiRx.create({ provider }).toPromise();

Getting the following error on create

Unable to decode Vec on index 0 createType(ExtrinsicV1):: createType(Call):: Calling Call.findFunction before extrinsics have been injected.

Working fine after clean install watchman watch-del-all && rm package-lock.json && rm -rf node_modules && rm -rf $TMPDIR/metro-* && rm -rf $TMPDIR/haste-map-* && NODE_OPTIONS=--max_old_space_size=8192 npm install

But,
header.blockNumber is undefined, header.number gives block numbers instead.

import { ApiRx, WsProvider, ApiPromise } from '@polkadot/api';
 var provider;
 var api;
        try {
            provider = new WsProvider(rpcServer);
            api = await ApiRx.create(provider).toPromise();
        } catch (error) {
            console.log(error);
   }
  api.rpc.chain.subscribeNewHeads().subscribe((header) => {
          console.log(`Chain is at #${header.blockNumber}`);
          console.log(`Chain is at #${header.number}`);
          console.log(`Chain is at #${header}`);
        });

header = {"parentHash":"0xecf52f1796f9f3b50bc92691967ebd6c0d29f07c8aaf17bb6c0fea9a5ee1bb13","number":259454,"stateRoot":"0x3f9e149a64f9531aebd2ce66366c8489ab192d3f45c1e0b2b6d733693746b551","extrinsicsRoot":"0x5a2cb032e3f3ac5af7747e66d6abeda0e70b2dfa5f41067eba1a886501198e39","digest":{"logs":["0x064241424544010300000085f2930f0000000067f60000","0x05424142450101e67bd36607f4ac701db9775f618c159544f589a88d6d7b2d74ba39d0c688b30d452b0c4299ece78df1a58ac472922673d0951b8dd796c85785b4b2b90b7b1881"]}}
