`ERROR: Condition "!p_data.has("baked_exposure")" is true.` when running project.

Tested versions

This is not a new issue. It appears to have existed for as long as Godot 4 has existed. It may even be an issue with the code (Demo) and not the engine.

Reproducible in: v4.3.dev.custom_build [1f0f81049] (Latest build from Master)
Reproducible in: 4.2.1 Stable
Reproducible in: 4.1 Branch - v4.1.4.rc.custom_build [68154d8a7]
Reproducible in: 4.0 Branch - v4.0.5.rc.custom_build [60867e63b]

In short, every version of Godot 4.

System information

Godot v4.3.dev (1f0f81049) - Windows 10.0.22621 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3080 Ti (NVIDIA; 31.0.15.5186) - AMD Ryzen 9 5900X 12-Core Processor (24 Threads)

Issue description

ERROR: Condition "!p_data.has("baked_exposure")" is true.
   at: LightmapGIData::_set_probe_data (scene\3d\lightmap_gi.cpp:209)

Steps to reproduce

Start the Global Illumination Demo project. The error should show up in the output immediately.

Minimal reproduction project (MRP)

Use the Global Illumination Demo project.

I was not able to find any version of Godot 4 that does not present this error, so I would not consider this a priority at all. Clearly we've all been living with this for a while.
