I'm getting the Algolia search request/query from the frontend into my Lambda function which then executes the request and returns the result. The format of the request is an array like

      [
        {
          "indexName": "indexname",
          "params": {
            "query": "querytext",
            "hitsPerPage": 7,
            "maxValuesPerFacet": 3,
            "page": 0,
            "facets": [
              "type"
            ],
            "tagFilters": "",
            "facetFilters": [
              "account_id:1"
            ]
          }
        }
      ]

After that I search using their API client

      const index = connectToIndex(ALGOLIA_APP,ALGOLIA_KEY,INDEX_NAME);
      const results = await index.search(requests);

Then the search query happens but I get 0 hits and when I console.log(results) the query field is deformed

{
  "hits": [],
  "nbHits": 0,
  "page": 0,
  "nbPages": 0,
  "hitsPerPage": 20,
  "exhaustiveNbHits": true,
  "exhaustiveTypo": true,
  "query": "[{\"indexName\":\"indexname\",\"params\":{\"query\":\"querytext\",\"hitsPerPage\":7,\"maxValuesPerFacet\":3,\"page\":0,\"facets\":[\"type\"],\"tagFilters\":\"\",\"facetFilters\":[\"account_id:1\"]}}]",
  "params": "query=%5B%7B%22indexName%22%3A%indexname%22%2C%22params%22%3A%7B%22query%22%3A%22querytext%22%2C%22hitsPerPage%22%3A7%2C%22maxValuesPerFacet%22%3A3%2C%22page%22%3A0%2C%22facets%22%3A%5B%22type%22%5D%2C%22tagFilters%22%3A%22%22%2C%22facetFilters%22%3A%5B%22account_id%3A1%22%5D%7D%7D%5D",
  "renderingContent": {},
  "processingTimeMS": 1
}

but the results should be like below (This is what I get when I console.log on express server and I get the desired hits. Notice how it sends an object with results field and the query attribute contains only the searched text)

{ results:
   [ { hits: [Array],
       nbHits: 20,
       page: 0,
       nbPages: 3,
       hitsPerPage: 7,
       facets: [Object],
       exhaustiveFacetsCount: true,
       exhaustiveNbHits: true,
       exhaustiveTypo: true,
       query: 'querytext',
       params:
        'query=querytext&hitsPerPage=7&maxValuesPerFacet=3&page=0&facets=%5B%22type%22%5D&tagFilters=&facetFilters=%5B%22account_id%3A1%22%5D',
       index: 'indexname',
       renderingContent: {},
       processingTimeMS: 1 } ] 
} 

My issue is why it console.log 2 different things on lambda and express. I'm sending in the same requests array and using the same algolia API search in both occasions.

My issue is why it console.log 2 different things on lambda and express. I'm sending in the same requests array and using the same algolia API search in both occasions.

• javascript
• amazon-web-services
• aws-lambda
• serverless-framework
• algolia

Ok it was a careless mistake
my connectToIndex returns an Algolia index

const connectToIndex = (appId,apiKey,index) => {
  const client = algoliasearch(appId,apiKey);
  return client.initIndex(index);
};

and I have done the search using index.search(requests) which implies client.initIndex().search(requests)

But for searching you don't call initIndex instead you call the search method of the client directly

client.search(requests)

I had correctly used this in express and somehow messed up inside the lambda
