problems of step return inconsistency

Hello,

I have a strange problem with my step result processing.

I have a step ("get all devices") that can return a list of devices. the result is always ["item1", "item2, ...] etc, even if I have only one item.

In a further step, I get this step's output and do a parsing :

items_list = jsonSlurper.parseText(items_list)

this works fine. I use this as the items can sometimes be listed as [{"uid1":"item1"}],etc.

The problem is that it sometimes fails because my input is incorrect.

If my first step provides me with two items or more ( ["item1", "item2, ...] ) the second step input (${get all devices#testResponse#$['result']}) gives me ["item1", "item2, ...] 

If my first step provides me with a single item (["item1]) the second step input is like [item1] => slight difference, but with the missing "" my json parsing fails

 

Does anyone knows why the format changes ?

  • I found a workaround, though I really would like to know why this happens.

    Here is the workaround :

     

    if (items_list.tokenize('[,]').size() == 1)
    {
        items_list = groovy.json.JsonOutput.toJson(items_list.tokenize('[,]'))
    }
    
    items_list = jsonSlurper.parseText(items_list)

    [item1] becomes ["item1"] and can be parsed properly
