Global shader parameter not found

[Bazouz660]

When exporting using the action, I get an shader compilation error stating that the "player_position" global shader variable doesn't exist, even tho it does:

the project.godot, the player_position variable is at the end of the file:

; Engine configuration file.
; It's best edited using the editor UI and not directly,
; since the parameters that go here are not all obvious.
;
; Format:
;   [section] ; section goes between []
;   param=value ; assign values to parameters
