CL-API Adapter Assistance (chainlink)

Hey, we are building a Chainlink API Consumer and need to also build an Adapter.

I am using this Chainlink Adapter Template:

I seem to be inputting the data wrong or have a stray ‘}’ in my input.

I was wondering if anyone knows what I’m doing wrong here, I could use a hand.

// Define custom parameters to be used by the adapter.
// Extra parameters can be stated in the extra object,
// with a Boolean value indicating whether or not they
// should be required.
const customParams = {
  base: ['data'],//base: ['base', 'from', 'coin'],
  quote: ['level'],//quote: ['quote', 'to', 'market'],
  endpoint: false,
  token_id: 0,
  address: '0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB'

const createRequest = (input, callback) => {
  // The Validator helps you validate the Chainlink request data
  const validator = new Validator(callback, input, customParams)
  const jobRunID =
  const endpoint = || 'price'
  //const url = `${endpoint}`
  const url = `${address}/metadata?chain=eth`
  const fsym = //.base
  const tsyms = //.quote

  const params = {

  // This is where you would add method and headers
  // you can add method like GET or POST and add it to the config
  // The default is GET requests
  // method = 'get' 
  // headers = 'headers.....'
  const config = {
    api_key: process.env.APP_ID

When I host it locally and run the Curl request I am getting a JSON error:

curl -X POST -H “content-type:application/json” “http://localhost:8080/” --data ‘{ “data”}’

 % curl -X POST -H "content-type:application/json" "http://localhost:8080/" --data '{ "data"}'

<pre>SyntaxError: Unexpected token } in JSON at position 8<br> &nbsp; &nbsp;at JSON.parse (&lt;anonymous&gt;...

I fixed my API-Key mistake but I am getting stuck here, if anyone knows.

curl -X POST -H “content-type:application/json” “http://localhost:8080/” --data ‘{“data”: “metadata”}’

{“jobRunID”:“1”,“status”:“errored”,“error”:{“error”:{“name”:“AdapterError”,“message”:{“error”:{“name”:“AdapterError”,“message”:“Required parameter not supplied: base”}}}},“statusCode”:500}%

It looks like says that base parameter was not present. I don’t know what that parameter should be
