Hi Olivia!

It's probably talking about the "workflowstep" object with identifier 8.  If you request the description of this workflow via the API (http://yourgalaxyinstance.org/api/workflows/<the id of this workflow>"), you'll be given the exact step identifiers to use.  In other words, unless this is the first workflow ever created on a brand new galaxy instance, your step ids will not be 0 and 1.

Dear developpers,

I'm trying to launch a small workflow using the api script workflow_execute_parameters.py

I have 2 steps: the input data step and a second step which needs a parameter called prefix.


The workflow is attached to this email.

I get an error on the parameters inputs which asks me to specify information about an 8th step (which does not exist)


Is there a test case available to use this script ?

Please keep me informed on that.

Have a nice day,
