Help with AMP setup -

[tinchisla]

Hi there,
I've use this tool for Standard creatives and it worked perfect. Now I'm trying to do the same for AMP.

In create_creatives.py, I've added just two lines in:

def create_creative_config(name, advertiser_id, video_ad_type, redirect_url):

snippet_file_path = os.path.join(os.path.dirname(__file__), "creative_snippet.html")
with open(snippet_file_path, "r") as snippet_file:
    snippet = snippet_file.read()

# https://developers.google.com/doubleclick-publishers/docs/reference/v201802/CreativeService.Creative
config = {
    "xsi_type": "ThirdPartyCreative",
    "name": name,
    "advertiserId": advertiser_id,
    "size": {"width": "1", "height": "1"},
    "snippet": snippet,
    "isSafeFrameCompatible": False,
    # la siguiente línea solo es en caso de AMP - comentar en caso de un creativo común
    "ampRedirectUrl": "https://acceleratedmobilepageurl.googleapis.com/v1/ampUrls:batchGet", # FIRST LINE
}

if video_ad_type:
    config["xsi_type"] = "VastRedirectCreative"
    config["duration"] = 1000
    config["size"] = {"width": "640", "height": "480"}
    config["vastXmlUrl"] = redirect_url
else:
    config["xsi_type"] = "ThirdPartyCreative"
    config["snippet"] = snippet
    config["isSafeFrameCompatible"] = False
    config["size"] = {"width": "1", "height": "1"}
      # la siguiente línea solo es en caso de AMP - comentar en caso de un creativo común

    config["ampRedirectUrl"] = "https://acceleratedmobilepageurl.googleapis.com/v1/ampUrls:batchGet" # SECOND LINE

return config

But, I'm getting this error:

k: self._PackArgumentsHelper(elem_arguments[k], v, set_type_attrs)

KeyError: 'ampRedirectUrl'

Definetely, I need help to config this for AMP. I really don't know what to do.
I could see that, I have to change the creative code type in GAM from Standard to Standard & AMP. I don't know how to do that with this tool. Is it possible?
Should I change anything else?
