Getting error while creating index for elastic search - node.js

Question

I am trying to create an elastic search index if it doesn't exist using OnModuleInit (NestJs). It works fine with my local machine but when I am trying to deploy to AWS ES Cluster, this part is giving such an error.
ElasticsearchModule.registerAsync({
useFactory: async () => ({
node: process.env.ES_ENDPOINT,
maxRetries: 3,
requestTimeout: 60000,
pingTimeout: 60000,
}),
})
export class ClientElasticSearchModule implements OnModuleInit {
constructor(private clientSearchService: ClientElasticSearchService) {}
async onModuleInit() {
await this.clientSearchService.createIndex();
}
}
It is where I am creating an index:
await this.elasticsearchService.indices.create({
index: clientsIndex,
body: {
settings: {
analysis: {...},
},
mappings: {
properties: {
name: {
type: 'text',
fields: {
complete: {
type: 'text',
analyzer: 'autocomplete_analyzer',
search_analyzer: 'autocomplete_search_analyzer',
},
},
},
},
},
},
});
Error message:

This looks like your AWS Opensearch (same tech under the hood of Elasticsearch) instance is returning a 403. This might mean you need to set up IAM Roles and the correct access for your instance. Please See the AWS Docs
