Hello, I am trying to save in a variable the response body of a POST Reques

Hello,
I am trying to save in a variable the response body of a POST Request, in a SAIL Interface. I first tried to use a!httpQuery (as I used to do for GET Requests), but POST method is not available.
I tried to use a!httpWrite function, but it needs to be trigered by a bind() function. The result is that I get "Invalid parameter: the parameter given as the 'set' parameter to the function 'bind' must not be null and must be a reference to a rule or function that returns Writer".
For testing purposes I tried also using Smart Service, and it works perfectly, but unfortunately it is not an option because of the usecase, so I need to make it work in SAIL.

Thanks in advance,
Octav

Not sure if you have reviewed how to use the bind() function at forum.appian.com/.../Evaluation_Functions.html but in case you haven't, that's a useful link.

I actually read the documentation for the bind() function, but this is the maximum I could get...
local!pass: bind(
get:
tostring(local!token),
set:
a!httpWrite(
url: "localhost/GetToken.aspx",
method: "POST",
body: "__RequestVerificationToken="&local!response.result.body&"&UserName=xxx&TokenTimeoutMinutes=20",
headers: {
a!httpHeader(
name: "Cookie",
value: local!response.result.headers["Set-Cookie"]
)
}
)
),

There are multiple examples on how to use bind at forum.appian.com/.../Connector_Functions.html. They are for the connectors but the idea is the same.

Would you mind looking at those examples to see how you need to update your expression? They show the use of a bind when using a writer function.
