I have some issue. I am testing the multi-instance support, as described here.
I have a simple process.
start -> task 1 -> task 2 -> end
when task 1 is executed it will send with the completion command, some variable (let’s call it items)
The name is “items”. In zeebe monitor the value can be seen it is [“b2e3a0a2-ca6c-4729-a46c-720268fdfe00”,“81ecfc98-0c10-4202-ab98-5b5c38daf5f2”], so an array directly not a JSON.
task 2, is multi instance, so on inputCollection I set “= items”
But when the task 2 is executed - I get an incident like “expected Array but found Null” on the data extraction.
I don’t understand what is the issue, my use case, seems exactly what is described in the link above.
The docker image I use to test this, is zeebe latest, updated today for me.
