I am creating an element with createTextNode and defining a text for it, I need to assign the name property to that element, however I can’t go through this vector

    const inputText = this.inputEl.value;

        if(inputText.length === 0)
            return;

        const response = await api.get(`/users/${inputText}/repos`);

        const mapped = response.data.map(repo => ({
            name: repo.name,
            description: repo.description,
            login: repo.owner.login
        }));

        repoUser[inputText] = mapped;

        this.repositories.push(repoUser);
        console.log(this.repositories);

        this.inputEl.value = "";
        this.render();
        // this.save();
    }

render() {
        this.project.innerHTML = '';

        // Criar a grade dos elementos
        let repos = document.createElement('div');
        repos.classList.add("repos");

        this.project.appendChild(repos)

        // let i = 0;
        this.repositories.forEach(function(repo) {
            // console.log(this.repositories.length)
            // while(i < this.repositories.length){
                let titleElement = document.createElement('h1');
                titleElement.appendChild(document.createTextNode(repo.login))

                repos.appendChild(titleElement);

                // Container dos itens
                let itemElement = document.createElement('div');
                itemElement.classList.add('repo-item');

                let titleItemElement = document.createElement('h3');
                titleItemElement.appendChild(document.createTextNode(toString(repo.name)));
                console.log(titleItemElement)
                // i++;
            // }

what happens is that I can’t go through this array nor access its properties.
