PkgTemplates does not execute my plugin

Hi! I create my own plugin:

struct Dependencies <: Plugin
    deps::Vector{AbstractString} = []
end

dependencies(d::Dependencies) = d.deps
function posthook(d::Dependencies, t::Template, pkg_dir::AbstractString)
    Pkg.activate(pkg_dir)
    Pkg.add(dependencies(d))
    Pkg.activate()
end

That should add deps to created toml. It works if I run the code of adding package externally, but when I add plugin as plugins=[Dependencies([“P”])] it seems like PkgTemplate does not execute it at all. I also wrote a test that also shows that the plugin is not working(maybe is not executed at all )

using TemplatePlugins: Dependencies, DefaultETLService
using Test

using Test
using Pkg: Pkg, PackageSpec, TOML
using PkgTemplates
using Suppressor: @suppress
using Random: Random, randstring

const USER = "tester"

Random.seed!(12)

tpl(; kwargs...) = Template(; user=USER, kwargs...)
pkgname() = titlecase(randstring('A':'Z', 16))

function with_pkg(f::Function, t::Template, pkg::AbstractString=pkgname())
    @suppress t(pkg)
    try
        f(pkg)
    finally
        PkgTemplates.version_of(pkg) === nothing || try @suppress Pkg.rm(pkg) catch; end
        rm(joinpath(t.dir, pkg); recursive=true, force=true)
    end
end

@testset "Dependencies plugin test" begin
    t = tpl(; plugins=[Dependencies(["PkgTemplates", "GitlabAPI"])])
    with_pkg(t) do pkg
        pkg_dir = joinpath(t.dir, pkg)
        toml = String(read(joinpath(pkg_dir, "Project.toml")))
        println(toml)

        @test contains(toml, "PkgTemplates")
        @test contains(toml, "GitlabAPI")
    end

    t = tpl(; plugins=[Dependencies([])])
    with_pkg(t) do pkg
        pkg_dir = joinpath(t.dir, pkg)
        toml = String(read(joinpath(pkg_dir, "Project.toml")))
        @test !contains(toml, "deps")
    end
end

end

all default plugins works
