Typescript Arrowjs Class 'RecordBatch<T>' incorrectly extends base class 'StructVector<T>'

[vikashsingh009]

I have imported arrowjs in typescript like

import { Table } from 'apache-arrow';

const arrow = readFileSync('simple.arrow');
const table = Table.from([arrow]);

but when i am building the project getting exception like

ERROR in node_modules/apache-arrow/ipc/reader.d.ts:236:5 - error TS2717: Subsequent property declarations must have the same type. Property 'schema' must be of type 'Schema', but here has type 'Schema'.

236     schema: Schema;
        ~~~~~~

  node_modules/apache-arrow/ipc/reader.d.ts:189:5
    189     schema: Schema<T>;
            ~~~~~~
    'schema' was also declared here.

Would you mind opening a Jira issue? Thanks

Hi @vikashsingh009, before opening a JIRA, can you please confirm if you're using version 2.0.0 of arrow, as this issue was opened in https://issues.apache.org/jira/browse/ARROW-8394, and was fixed with PR #8216, which was released on ~22 October.
