I am trying to run webhooks on FME Server. The webhooks run successfully and I get status code 200 from the server but when I check the length of the data in the response it is 0, in this case 0. Is there a header I am missing?

from urllib.request import urlopen
from shutil import copyfileobj

def runwebhook(runurl):
    response = urlopen(runurl)
    if response.getcode()==200:
        print("Success")
    return response

def savefilestream(filepath,response):
    if exists(filepath): remove(filepath)
    if isinstance(response.read(),bytes)==True:
        with open(filepath,'wb') as f:
            data = len(response.read())
            print(data)
            copyfileobj(response, f)
            f.close()
            print("File Saved Successfully")
    else:
        with open(filepath,'w') as f:
            f.write(str(response.read()))
            f.close()
            print("File Saved as text")

def runwebhookwithheaders(runurl,hooktoken):
    runresponse = None
    headers = {
    'Authorization':f"fmetoken token={hooktoken}",
    'Accept': 'application/octet-stream',
    'Content-Type': "application/octet-stream",
    'accept-encoding': "gzip, deflate",
    'Content-Transfer-Encoding': 'binary',
    'Connection': "keep-alive"
    }
    req = Request(self.runurl,headers=headers)
    try:
        runresponse = urlopen(req)
    
    except HTTPError as e:
        print(e.code)
        print(e.code)
    except URLError as e:
        print(e.reason)
        print(e.reason)
    return runresponse

#example usage for a simple webhook
filepath= r":\filepath\\"
runurl = "%%Webhookurl%%"
resp = runwebhook(runurl)
savefilestream(filepath,resp)

# example with token
filepath= r":\filepath\\"
runurl = "%%Webhookurl%%"
hooktoken = "token"
resp = runwebhookewithheaders(runurl,token)
savefilestream(filepath,resp)
