400 Bad Request in Postman GET

[Richard_Quintan]

Hello there, 

I've developed a workflow that follows these steps:

1) When a record is updated, all the product's fields are watched

2) With these watched fields, a new script will run. The main goal with this script is taking the product's information, then making a PUT request to an external JSON API by taking the product's SKU.

When I test the script, it runs successfully, but the response logs: 

{status: 400, message: "Invalid data provided"}

1.  status: 400
2.  message: "Invalid data provided"

Does anyone knows why this is happening? Is it an error in Airtable or in the external API server? Thanks in advance!

The code goes like this:

//input of modified product

let inputConfig = input.config();

//Fetch for external API and JSON creation

let response = await fetch(`http://.../${inputConfig.sku[0]}`, {
    method: 'PUT',
    body: JSON.stringify({
      "product": {
        "ean": inputConfig.ean[0],
        "sku": inputConfig.sku[0],
        "name": inputConfig.name[0],
        "brand": inputConfig.brand[0],
        "short_description": inputConfig.short_description[0],
        "description": inputConfig.description[0],
        "cost_price": inputConfig.cost_price[0],
        "price": inputConfig.price[0],
        "gd_size_reference": inputConfig.gd_size_reference[0],
        "track_inventory": inputConfig.track_inventory[0],
        "available_on": inputConfig.available_on[0],
        "tax_category_id": inputConfig.tax_category_id[0],
        "stock_items_attributes": [
          {
            "stock_location_id": inputConfig.stock_location_id[0],
            "count_on_hand": inputConfig.count_on_hand[0],
          }
        ],
        "taxon_ids": [
          {
            "taxon_id": inputConfig.taxon_ids[0],
          }
        ], 
      }
    }),
    headers: {
        'Authorization': 'eyJh...',
    },
});
console.log(await response.json());

Perhaps JSON does not match the data structure of the external API.
Need to check the documentation.
