Form submit redirect results in "Content missing"

[chapterjason]

As I tried to use this project, I came across the issue that if I submit the form and everything is alright, it returns like this:

return $this->redirectToRoute('project_show', ['id' => $project->getId()]);

Which ends up in:

(Content missing was the form before submit)

A bit of research I found something about missing frame in the Turbo Handbook

But not sure how to solve it properly, my current workaround is to add this and a block into the base template.

{% block meta %}
    <meta name="turbo-visit-control" content="reload">
{% endblock %}

I was having this issue as well. What I learned by testing is, I belive you need a matching turbo-frame around the content you want displayed on a successful form submission, that matches the ID of the turbo-frame your form is contained in.

When I did this, my content displayed as expected.
