> [JavaScript] Incorrect type resolution in nested schemas
> --------------------------------------------------------

> Key: AVRO-4173
> URL: https://issues.apache.org/jira/browse/AVRO-4173
> Project: Apache Avro
> Issue Type: Bug
> Components: javascript, js
> Reporter: Tyler Harwood

> Priority: Major
> Labels: pull-request-available
> Fix For: 1.13.0

> Time Spent: 2h 10m

> Namespace inheritance is broken when parsing nested record types with mixed
> explicit and inherited namespaces. This causes type resolution to fail with
> "undefined type name" errors.
>
> Example code to reproduce the bug:
> {code:java}
> const avro = require('avro-js');
> const schema = {
> type: 'record',
> name: 'Parent',
> namespace: 'parent.ns',
> fields: [
> {
> name: 'child_field',
> type: {
> type: 'record',
> name: 'Child', // No namespace - should inherit 'parent.ns'
> fields: [{name: 'value', type: 'int'}]
> }
> },
> {
> name: 'other_field',
> type: {
> type: 'record',
> name: 'Other',
> namespace: 'different.ns', // Explicit namespace corrupts context
> fields: [{name: 'data', type: 'int'}]
> }
> },
> {
> name: 'reference_field',
> type: 'Child' // References Child - should resolve to 'parent.ns.Child'
> }
> ]
> };
> // This fails with "undefined type name: different.ns.Child"
> const type = avro.parse(schema);
> {code}
>
