Hello! I have a strange issue. We’re creating a bunch of snippets. One strange behaviour we noticed is: If you are using a custom plugin, an array output won’t work on a loop.
Here’s an example. I created a plugin that merely outputs an array of strings such as []string.
Using that action on a workflow works fine. The action outputs the array and I can use that array in a Loop Action.
However, if I add that same action on a snippet, the variable is NOT available to loop over. At first I thought I had a complex array of objects and R7 was complaining about something but even an action that simply returns a list of strings won’t work. Again, in a workflow this works fine.
Two interesting behaviours:
-
R7 plugins seem to work fine. I was using the
string to listplugin to test and it works fine, the variable appears to be looped over just fine. I even inspected itsplugin.spec.yamlto see if it was doing anything different, but it isn’t. It simply defines an output that is an array. -
If I am on the snippet and I edit the output (via the UI) of the action to have any change, the variable suddenly appears to be looped over.
For example, let’s say I have this output:
texts: string
some_var: string
If I change some_var to be an integer, the variable “texts” magically appears on the loop step. If I change some_var to be a string again, the variable disappears on the loop step.
Anyone has any light to shed? It seems to be a bug.
