Issue when running recon on mac addresses

[TotallyNotAHaxxer]

When running option 1 on the recon section in the tool, I got the following error when I selected a captured MAC.

SCANNING MAC ADDRESS...
Traceback (most recent call last):

I am assuming this is a decoding error from the API that is used on the backend which is called from one of the scanning functions.

def address_api_call(address, ip_address):
    print_output('\n SCANNING MAC ADDRESS...')
    url = ("https://macvendors.co/api/" + address)
    response=requests.get(url)
    result=response.json()
    if result["result"]:
        json_object=result['result']
        if "error" in json_object:
            print_output("\n No MAC Address Found!")
            return()
        transcribe_api_results(json_object, ip_address)
    else:
        print_output("\n ERROR: Something Went Wrong")
