Invalid bus index "-1" error when converting 4.2 project to 4.3

Strange! Remaking the bus worked! The difference between the two files is weird tho, despite being the same the last line of the .tres is different original ends with bus/2/send = &"SFX" and an exact remake ends with bus/2/send = &"Master" No idea what to make of this but the problem seems solved!

I did. It's vague at best and the solution of deleting default_bus_layout and having it make another (at least I think that's what happened) didn't do anything.

This is my default bus layout:

[gd_resource type="AudioBusLayout" load_steps=2 format=3 uid="uid://d2g54ov0s262o"]

[sub_resource type="AudioEffectLowPassFilter" id="AudioEffectLowPassFilter_gr1t2"]
resource_name = "LowPassFilter"

[resource]
bus/0/volume_db = 6.02
bus/1/name = &"SFX_1"
bus/1/solo = false
bus/1/mute = false
bus/1/bypass_fx = false
bus/1/volume_db = 0.0
bus/1/send = &"SFX_2"
bus/2/name = &"SFX_2"
bus/2/solo = false
bus/2/mute = false
bus/2/bypass_fx = false
bus/2/volume_db = 2.05151
bus/2/send = &"SFX_1"
bus/2/effect/0/effect = SubResource("AudioEffectLowPassFilter_gr1t2")
bus/2/effect/0/enabled = true
bus/3/name = &"Music"
bus/3/solo = false
bus/3/mute = false
bus/3/bypass_fx = false
bus/3/volume_db = 0.0672607
bus/3/send = &"Master"

For me I had to rebuild my bus setup. Make sure to delete default.bus.layout.tres. Then, hit Create here to start from scratch.

#

For whatever reason, that fixed it.

#

You can save a copy of the old bus layout elsewhere to cross reference and make sure you're setting up the new one correctly.
