Typescript: @fastify/elasticsearch does not accept older client

[jatin2-kumar]

Hi Team,
I need to use a previous version of the client while registering the fastifyelasticsearch in typescript.
I am doing it like this

import fp from 'fastify-plugin';
import fastifyElasticsearch from '@fastify/elasticsearch';
import { Client } from '@elastic/elasticsearch';

export default fp(async (server) => {
  try {
    await server.register(fastifyElasticsearch, {
      client: new Client({ node: 'http://localhost:9200' }),
    });
  } catch (error) {
    server.log.error(error, 'Failed to initialize Elasticsearch');
    throw error;
  }
});

But it is giving me an error for the new Client :

No overload matches this call.
  Overload 1 of 3, '(plugin: FastifyPluginCallback<FastifyElasticsearchOptions, RawServerDefault, FastifyTypeProviderDefault, FastifyBaseLogger>, opts?: FastifyRegisterOptions<...>): FastifyInstance<...> & PromiseLike<...>', gave the following error.
    Type 'Client' is missing the following properties from type 'Client': diagnostic, name, helpers, asyncSearch, and 72 more.
  Overload 2 of 3, '(plugin: FastifyPluginAsync<FastifyElasticsearchOptions, RawServerDefault, FastifyTypeProviderDefault, FastifyBaseLogger>, opts?: FastifyRegisterOptions<...>): FastifyInstance<...> & PromiseLike<...>', gave the following error.Overload 2 of 3, '(plugin: FastifyPluginAsync<FastifyElasticsearchOptions, RawServerDefault, FastifyTypeProviderDefault, FastifyBaseLogger>, opts?: FastifyRegisterOptions<...>): FastifyInstance<...> & PromiseLike<...>', gave the following error.
    Type 'import("/node_modules/@elastic/elasticsearch/index").Client' is not assignable to type 'import("/node_modules/@fastify/elasticsearch/node_modules/@elastic/elasticsearch/lib/client").default'.

    Type 'import("/node_modules/@elastic/elasticsearch/index").Client' is not assignable to type 'import("/node_modules/@fastify/elasticsearch/node_modules/@elastic/elasticsearch/lib/client").default'.ts(2769)

Can you help here to solve this issue?

Your Environment

• node version: v18.15.0
• fastify version: >=2.0.0
• "@elastic/elasticsearch": "^5.6.22",
• "@fastify/elasticsearch": "^3.1.0",
• os: Mac

The plugin has this version: "@elastic/elasticsearch": "^8.2.1",
https://github.com/fastify/fastify-elasticsearch/blob/master/package.json#L31

I'm not a TS user - can't suggest anything better than adding as any

[jatin2-kumar]

yes, the plugin has this version: "@elastic/elasticsearch": "^8.2.1", but i need to use a old version for client so thats why using the older version.

I would actually recommend to fork this plugin and patch it correctly.
