Weird behavior of Web-API in 17.1

Hi,

1)
I found a weird behavior while using Web-API in 17.1 , when i was using the same API in 16.3 it was able to work perfectly, but in 17.1 it's causing an issue.

2)
Also i found, when i am trying to consume a Web-API of type POST using httppost() it gives me an error saying "Incorrect user name or password. Please check your credentials and try again" i tried using a!httpAuthenticationBasic() for authentication, but the same issue. i tried switching from httppost() to httpWrite() here also the same issue, whereas when i tried invoking the same POST service using httpost() or httpWrite() in 16.3 it worked well.


Did anyone face the same issue while working with 17.1, i know it's a recent released one, so Appian will be releasing some hotfixes, but just wanted to know did anyone else also encountered the same issue.
