If statement not working

[HenBOMB]

Bug Description

How do I explain this?
The if statement is returning "true" as shown but during execution / runtime its failing as if it were false?

To Reproduce

1. Add chat trigger and create an agent node and check intermediate steps.
2. Connect an if statement to the output and paste expression: {{ JSON.parse($('Your Agent').first().json.intermediateSteps[0].observation).some(x => JSON.parse(x.response?.[0]?.text)?.[0].results != null) && !$('Your Agent').first().json.intermediateSteps.some(x => x.action.messageLog[0].kwargs.tool_calls[0].args.tool === 'SomeTool')}}
   (annoying to parse so many times but ok)
3. Implement "SomeTool" that outputs { results: [] } and connect it to the agent.

Expected behavior

The if statement should fail as shown in the screenshot.
Even if it shows true its truly not because its failing.

@HenBOMB Could you provide more information about the issue you are experiencing?

Using the workflow above, the IF statement worked as expected. With the first case scenario input, the expression returned true and the execution continued from true branch. Similarly, in the second case scenario input, the expression returned true and continued from true branch. I have attached some images for your reference.

[HenBOMB]

My bad, replace SomeTool in the expression with SendCard.
If not the expression will ALWAYS output true, unless the agent never calls the Events tool and there is no { results: [] } for the expression to check for.
I ran the agent node during execution to generate the output. It's not a test execution cause that works and doesn't reveal the bug.

[HenBOMB]

I have created a workflow with the reproducible bug for simplicity.
Here I have the results from both case tests in the workflow:

First case

Second case

Before running the workflow make sure you change the HTTP request's URL and change the AI Agent Tools MCP endpoint with your domain.
