I am trying to use the below function to access the daily market prices from the refinitiv data API. However, at session.open() I get an error - in the _utils.py, " ValueError: Proxy keys should use proper URL forms rather than plain scheme strings. instead of "qualys_http", user "qualys_http://"
Can some one help me with resolving this issue. Thanks.
Error
It shouldn't relate to the Refinitiv Data Library. It could be the problem in the Python environment. You can test the connection with the following code.
import requests
url = "https://api.refinitiv.com/auth/oauth2/v1/token"
payload = 'username=<username>&password=<password>&grant_type=password&scope=trapi&takeExclusiveSignOnControl=true&client_id=<client_id>'
headers = {
'Content-Type': 'application/x-www-form-urlencoded'
}
response = requests.request("POST", url, headers=headers, data=payload)
print(response.text)
Thank you for reaching out to us.
According to the error, it may relate to the proxy settings.
Please check that if you are using a proxy server on the machine and what the qualys_http is.
@Jirapongse thanks for the reply. I am running this on a dev machine VDI, on Amazon Workspace. Perhaps the issue come because of this? 
According to the error, it is about the proxy settings.
Sorry, I can't test it. I don't have an access to that environment.
@Jirapongse I was able to manage the proxy issue, but I am getting the below error now
would you happen to know what might be causing this?
