Is there a way to conditionally use qs params?

[nullsocket]

My usecase is pagination, first request never has qs param but provides a token

Currently I've tried to use a variable from context.vars in the url and setting that variable in processors, but it seems like artillery.io doesn't like that.

I've had partial luck with ifTrue using the variable I set for pagination and having one request built out like(for brevity pseudo code I'm on mobile at moment) :

• get:
  ifTrue: not pageToken
  url: "/users"

• get:
  ifTrue: pageToken
  url: "/users"
  qs:
  next: "{{ pageToken }}"

And another request without qs for the initial one, however it seems like it gets only 2 tokens in before one of the vUsers just doesn't seem to see the pageToken and calls the first request again resetting the page token.

Should I be tracking every single vUsers pageTokens independently?
