Trying to *optionally* select a random ID - getting: jsonPath($.documents[*].id).findAll.transform.exists, found nothing

Hey,

So basically a business rule is that users can optionally have documents, but it’s acceptable to not have any documents in the JSON payload.

I’m trying to grab a random document and if we find one, then the second doIf() kicks in to request that document

Lines 8-12 here are doing this so far: https://gist.github.com/dragoonis/665343a9ea13eba127416aa8038d1f6f#file-test-scala-L8-L12

When the JSON payload has “documents: []” as an empty array (valid response)`
Line 8 here is causing the error: https://gist.github.com/dragoonis/665343a9ea13eba127416aa8038d1f6f#file-test-scala-L8

What’s the solution here to:

  1. make it optional to have documents
  2. choose a random document

Many thanks,
Paul

Hi Stephane,

I’m not yet on 3.0 but on the latest 2.x release.

Can you advise on how to approach the situation differently? Right now this is a blocker for me.

Many thanks,
Paul

Hi Stephane,

I’m upgrading to 3.0.0 right now, so that you’ll help me.

I’ve got a syntax issue with 3.0.0 upgrade and I’ve created a post on this.

Many thanks,
Paul
