ReAct agent (only?) previous [null] that is passed in Set gets passed as null to tool, breaking is not empty

[Morriz]

Bug Description

What the title says.

To Reproduce

test_output.json
test_input.json

1. activate the test output workflow
2. trigger test input
3. observe in test output that the if node can't make sense of the test prop's value

Expected behavior

The ReAct agent to not mess with values. I hope the recent refactoring of this agent has fixed this, but maybe my bug report is just in time to get a fix shipped ;)

Hey @Morriz,

We have created an internal ticket to look into this which we will be tracking as "GHC-454"

Hi @Morriz

Can you provide more information here as well? It's unclear what you mean by "test output workflow". A workflow JSON with minimal working example would be appreciated.

Also, we recommend users to move away from ReAct agents, and use Tools agents as much as possible; ReAct agents are not as reliable.

[Morriz]

@jeanpaul ?? I find react agents to be MORE reliable and I have switched to that from tools agents.

I will provide my workflow here in a bit

@jeanpaul I never saw I did not correctly add the test workflow files in my OP, but have added it now.
