AI Agent tool - callin.io workflow gives single output instead of array

Hi,

I have an AI Agent with access to the "call callin.io workflow" tool. My sub-workflow output provides multiple items, but within the main workflow, I'm only receiving the very first item. What might I be doing wrong? Is it possible to retrieve multiple items and utilize them with the AI Agent?

I'm sharing a much smaller and simpler version of my AI Agent.

Subworkflow output:
json
[
{
"eventId": "094rg6l00uqkdd3tqnop6ssvcu",
"date ": "2025-02-26T12:45:00+01:00"
},
{
"eventId": "2nnhd76ri74iqj2duvg5kngf2c",
"date ": "2025-02-26T16:30:00+01:00"
},
{
"eventId": "28kl2dk4c68tvaoogai3muupbu",
"date ": "2025-02-26T18:45:00+01:00"
}
]


Main workflow output using "call callin.io workflow":
json
[
{
"eventId": "094rg6l00uqkdd3tqnop6ssvcu",
"date ": "2025-02-26T12:45:00+01:00"
}
]


Thanks for your help.
