Running Hello Zig Build, error: no field named 'root_source_file' in struct 'Build.ExecutableOptions'

when running example given in https://zig.guide/0.12/build-system/zig-build

build.zig:6:10: error: no field named 'root_source_file' in struct 'Build.ExecutableOptions'
        .root_source_file = .{ .path = "src/main.zig" },
