Flow Builder UI Bug: "Save Log" toggles vanish after 3 seconds in Sandbox & Dev Orgs (v4.18.3)

New Bug Summary

Hi team! First off, thanks for all the work on this amazing tool.

I’m running into a really frustrating UI quirk in Flow Builder and wanted to flag it. I know this might ultimately be a Salesforce Lightning rendering issue, but it is currently blocking the ability to configure the log actions through the standard UI.

The Problem:

When I add the "Add Log Entry" action to my Flow canvas, the optional input toggles (like Save Log and Save Method) show up for about 3 seconds when the properties panel first loads. But right after that, they completely disappear from the screen, making it impossible to turn them on or configure them. I have verified that this happens in both my Sandbox environment and my personal Developer Edition org.

Steps to Reproduce:

1. Install the Nebula Logger v4.18.3 Unlocked Package in a Sandbox or Dev org (see the attached "installed nebulla logger" image).
2. Open Flow Builder, create a Flow, and drop the Add Log Entry action onto the canvas.
3. Look at the right-hand properties panel: the toggles load initially (see the attached "toggle visible" image from my Sandbox).

Wait about 3 seconds, and the toggles completely vanish (see the attached "toggle not visible" image).

What I expected:

The toggles should stay visible so I can switch them to "Included" and set my variables. (I tried using the 'Tab' key to force the UI to focus on the hidden fields, but it didn't work).

My Environment:

Nebula Logger Version: v4.18.3 (Unlocked Package)
Salesforce Environment: Sandbox & Developer Edition Org
Browser: Chrome

I've attached the screenshots below showing the exact disappearing sequence. Let me know if you need any more info or if there is a known workaround to force Flow Builder to display these! Thanks!

Here are the screenshots showing exactly what is happening:

1. Installed Package: Showing Nebula Logger v4.18.3 successfully installed in the org.

2. Toggles Visible: The properties panel immediately after adding the action, showing the optional toggles present on the screen.

3. Toggles Vanished: The exact same panel about 3 seconds later, with the toggles completely gone.

Hi @AniTheWizNo1 - this sounds like the same issue as #997, does that sound correct to you?

Hi @jongpie

Yes, the visual UI bug is exactly the same as #997

There are just two small differences in my case:

1. I am using the Unlocked Package, while they are using the Managed Package.
2. I haven't hit the NullPointerException I was receiving An Apex error occurred: System.StringException: Invalid id

@AniTheWizNo1 thanks for the info! For now, I'll keep both issues open since you're experiencing a few small differences.

For the error System.StringException: Invalid id, would it be possible for you to provide the full exception/stack trace, or ApexLog? And just to confirm - in your screenshot, it looks like you're not passing a value for (Optional) Record ID correct?
