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.

That error usually means Appian-Locust isn’t completing the full auth flow, even if your credentials are correct. If your Appian setup uses SSO (SAML/Okta/OAuth), the default login script won’t handle the redirects properly, which is why it only finds the JSESSIONID cookie. Double-check the exact login endpoint you’re hitting and enable debug logs to see the full response/redirect chain. In most cases, it’s an authentication flow mismatch rather than a credential issue.
