To Reproduce

1. Execute this code:
   const eosjs = require('eosjs');
   const fetch = require('node-fetch');
   const rpc = new eosjs.Rpc.JsonRpc('http://127.0.0.1:8888', { fetch });

(async (account_name) => {
result = await rpc.get_code(account_name);
console.log(result)
})("eosio")

@stefanzarembinski Hello,
Can you please elaborate on the problem? Getting WAST via get_code was deprecated in 1.2.0 and removed in 1.2.2.

[stefanzarembinski]

Getting WAST via get_code was deprecated in 1.2.0 and removed in 1.2.2. Yet the
'rpc.get_code(account_name)' function seems to ignore the fact, and attempts to return
WAST, running into troubles.

To reproduce, having a node listening, with a node prompt, do:

const eosjs = require('eosjs');
undefined
const fetch = require('node-fetch');
undefined
const rpc = new eosjs.Rpc.JsonRpc('http://127.0.0.1:8888', { fetch });
undefined
(async (account_name) => {
... result = await rpc.get_code(account_name);
... console.log(result)
... })("eosio")
Promise {
,
domain:
Domain {
domain: null,
_events:
{ removeListener: [Function: updateExceptionCapture],
newListener: [Function: updateExceptionCapture],
error: [Function: debugDomainError] },
_eventsCount: 3,
_maxListeners: undefined,
members: [] } }

I see, this can be misleading:
To reproduce, having a node listening, with a node prompt

I mean:
... having a local eosio node running ...

Added argument to default code_as_wasm to true, to be consistent with how things work today...
