No, if you wanted to evaluate the literal string you'd need to use
${literal("REST_URL")}
When you use ${REST_URL:endsWith("...")} you are testing whether or not the
value of the REST_URL
variable ends with ...
Think of it the same as just using the expression ${REST_URL} -- you expect
that to return the value of the REST_URL
variable, not the string literal "REST_URL". In your case, you're then just
chaining together more EL calls.

Doesn't seem to make much sense: the plan is to run "endsWith" on value of
REST_URL, doesn't your expression set to tun it on literal string "REST_URL"
within {...} ?
Thank you,

Hello,
The issue appears to be that you're using `${${REST_URL}:endsWith`
at the beginning, which is saying "resolve the value of the REST_URL variable,
then use that as the name of a variable."
So it's looking for a variable named "http://localhost:8080/nifi-api"; and never
finds it. So endsWith() evaluates to `false`
in all cases.
What you want is instead:
${REST_URL:endsWith('/'):ifElse('${REST_URL}resources','${REST_URL}/resources')}
I.e., check if the value of the REST_URL variable ends with a slash...
Thanks

I am using processor group variable as base part of my URL:
REST_URL=http://localhost:8080/nifi-api
I am trying to append second part of URL in InvokeHTTP regardless if REST_URL
ends with '/', or not so that concatenation of
"http://localhost:8080/nifi-api/";, or "http://localhost:8080/nifi-api"; with
"resources" return the same URL: "http://localhost:8080/nifi-api/resources":
${${REST_URL}:endsWith('/'):ifElse('${REST_URL}resources','${REST_URL}/resources')}
But the expression always appends '/', so in the first case I end up with
"http://localhost:8080/nifi-api//resources";... Any idea where the error is?
Thank you,
