Create "id" property from API that needs to be parsed to an int

I am trying to fix the “Got a result missing the "id" property” issue.

return z.request(options)
  .then((response) => {
    response.throwForStatus();
    const results = response.json;
    const sales = results["data"].map((item) => {
      return {
          ...item,
          id: item["record_id"],
      };
    });
    console.log(sales);
    return sales;
  });

In the code above, the “record_id” in our API contains a prefix of either “a_” or “t_” or “d_”. This means a “record_id” could be “a_123456”. I try to address it with:

return z.request(options)
  .then((response) => {
    response.throwForStatus();
    const results = response.json;
    const sales = results["data"].map((item) => {
      return {
          ...item,
          id: item["record_id"].replace("a_",10).replace("t_",11),
      };
    });
    console.log(sales);
    return sales;
  });

However, when I view the output I get an error of: 

Invalid API Response: - Got a two or more results with the id of "10"

I would think it should return “10123456” based on the example above. Any input on why it’s not working properly? I’ve tried this in JSFiddle and it works fine.
