[BUG] `Select Output` feature of chat doesn't work

[PlaneInABottle]

Describe the bug
When I select output fields while using chat, the agent block's response doesn't give me the outputs filtered.

To Reproduce
You can directly try using chat's select output, it directly doesn't work.

Expected behavior
The output should include the fields only that I select.
