When trying to copy an artifact from a sibling job using "downstream to" selector I get the following error:

}}{{ERROR: Unable to find a build for artifact copy from: poc/downstream.copy.producer
 
Scenario
 
3 jobs

• Parent job - MultiJob - Just triggers or schedules a set of jobs
• Producer job - Freestyle job - Triggered by parent job as Phase 1
• Consumer job - Freestyle job - Consumes data produced by producer and is triggered as Phase 2 by parent job

Configuration

• Producer job: 

• • Generates a sample file
  • Archives the file and stores fingerprints
• Consumer job:
  • Receives the parent build number
  • Copies sample file from producer job based on the job being downstream of the provided number
• Parent job:
  • Stage 1: Trigger the producer
  • Stage 2: Trigger the consumer

Selector used: "Downstream to"

Side note: Tested the same scenario without folders
