I guess it's expecting some content in the "Content" textarea field on the "Edit Campaign" screen. Try just putting any random string in there if the content field isn't used in your template.

You can fix it by adjusting the code of sendportal-core to this:

if ($this->template_id) {
            return str_replace(['{{content}}', '{{ content }}'], $this->content ?? '', $this->template->content);
}

or you can type anything into the "Content" field. It doesn't be a "content" string as suggested by @GwilCodes, it can be any string.
