Login unsuccessful exception on Appian-Locust

Hi,

I am new to Appian-Locust, I have installed Appian Locust, executed a login script for Appian URL and I am getting this exception "Login unsuccessful, no multipart cookie found, only found <RequestsCookieJar[<Cookie JSESSIONID....". I checked my credentials and they are working fine when login manually. I have tried executing the same Appian URL via generic Locust and there is no such exception shown.

Can anyone help here.

As per their documentation if you are seeing this error then to resolve it - 

  • Verify username and password in auth are correct for your Appian site

  • Verify the user has appropriate permissions to access the site, try in a browser

Happy to help. Even happier to optimize.
