Question

I have a custom file importer, and this is my import method, it simply places each line of the file in a PackedStringArray in a resource. The resource saves and everything is well, but when in project, the PackedStringArray is printed as empty ( [ ] ).

In the .godot/imported, the tres file does not have the content either.

func _import(source_file, save_path, options, platform_variants, gen_files):
	var file = FileAccess.open(source_file, FileAccess.READ)
	if file == null:
		return FAILED
	var csl = CSLScript.new()
	while file.get_position() < file.get_length():
		csl.lines.append(file.get_line())
	var filename = save_path + "." + _get_save_extension()
	return ResourceSaver.save(csl, filename)

Is your csl.lines property exported?
