Javascript – Error: Extracting Data from Request Body in MongoDB Serverless Function

When working with a MongoDB serverless function, I encountered a challenge while trying to extract data from the request body. The process resulted in unexpected errors that needed to be addressed in order to properly handle the data.

Upon attempting to access the data from the request body using body.Data, an error occurred. Despite the presence of data in the body, the method of retrieval triggered the error, preventing successful extraction.

I encountered an issue while attempting to extract data from the body of a request, which resulted in errors. To address this problem, I made an attempt to retrieve the body data separately.

Here is the code snippet I used for my MongoDB serverless function:

The problem arises when trying to access the data from the body

Sample code for the MongoDB serverless function

  exports = async function({ query, headers, body }, response) {
  const  bodyData = body.Data;
  
  return { body, bodyData };
};

An error occurs when attempting to retrieve data using body.Data

`

{
  "body": {
    "Subtype": 0,
    "Data": "W3sNCiAgImV4Y2VycHQiOiAiTmV3IEV4Y2VycHQiLA0KICAiZGVzY3JpcHRpb24iOiAiTmV3IERlc2NyaXB0aW9uIiwNCiAgImltYWdlVXJsMSI6ICJodHRwczovL2V4YW1wbGUuY29tL2ltYWdlLmpwZyIsDQogICJpbWFnZVVybDIiOiAiaHR0cHM6Ly9leGFtcGxlLmNvbS9pbWFnZTIuanBnIiwNCiAgImltYWdlVXJsMyI6ICJodHRwczovL2V4YW1wbGUuY29tL2ltYWdlMy5qcGciLA0KICAiZGF0ZSI6ICIyMDIzLTA3LTE0IiwNCiAgImNhdGVnb3J5IjogIlRlY2hub2xvZ3kiLA0KICAidHJlbmRpbmciOiB0cnVlLA0KICAidG9wUGljayI6IGZhbHNlLA0KICAicG9wdWxhciI6IHRydWUNCn1d"
  },
  "bodyData": {}
}

`

There is data available in the body. However, accessing the data through body.Data is causing an error

    I found a solution for the error code/issue I asked before!

    Here's how I solved the error code/issue:

    exports = async function({ query, headers, body }, response) {
const result = JSON.parse(body.text())
return { result };

    }

    I hope this helps others who encounter the same problem

    The issue you encountered might be related to the format of the data in the request body. It appears that the body.Data value is a Base64-encoded string. To access the actual data, you need to decode the Base64 string.

    Updated code:

    exports = async function({ query, headers, body }, response) {
  const dataBuffer = Buffer.from(body.Data, 'base64');
  const decodedData = dataBuffer.toString('utf8');
  
  return { body, decodedData };
};

    Now, when you access decodedData, it should contain the decoded data from the Base64 string in the request body. Make sure to use decodedData instead of bodyData in your further processing.
