joedixon/laravel-translation not updating

I have just installed a Joedixon/Laravel-translation package in Laravel version 8. It shows the words but when I want to update it will not work. I did everything that was said in the documentation and also I've read this article about it but it also didn't work. https://github.com/joedixon/laravel-translation/issues/82

NOTES:

1: I changed the driver to database.

2: adding a new Language works fine

3: while adding new translation it searches in http://localhost/languages/en instead of http://localhost/project_name/languages/en

When I try to update a word it says 404 not found in the console: Routes:

Solution

I solve the Problem which was completely in different place

it's in public/vendor/translation/js/app.js

        methods: {
            setActive: function () {
                this.isActive = !0, this.$refs.trans.focus()
            },
            storeTranslation: function () {
                var e = this;
                this.isActive = !1, this.hasChanged && (this.isLoading = !0, window.axios.post
                    ("/MY_PROJECT_NAME/public".concat("/").concat(this.route, "/").concat(this.language), {
                    language: this.language,
                    group: this.group,
                    key: this.translationKey,
                    value: this.translation
                }).then((function (t) {
                    e.hasSaved = !0, e.isLoading = !1, e.hasChanged = !1
                })).catch((function (t) {
                    e.hasErrored = !0, e.isLoading = !1
                })))
            }
        },

just added ("/MY_PROJECT_NAME/public".concat("/") and the problem solved
