Array_replace_recursive(): Expected parameter 2 to be an array, string given

How do I debug this? I clicked page two on my website and I get the following error.
0 - An exception has been thrown during the rendering of a template ("array_replace_recursive(): Expected parameter 2 to be an array, string given")

I am running the latest grav version 1.7 with the following template SoraArticle v1.5.1

I got the logs in the admin and a little hard to pinpoint the problem. It seems to be a problem with a blog template block content.

@codevista, I'm sorry, but I cannot reproduce the issue...

• Downloaded skeleton SoraArticle
• Browsed the website
  • Clicked page 2 of blog: No issues.
• Upgraded Grav and plugins
  • $ bin/gpm selfupgrade
  • $ bin/gpm update
• Browsed the website
  • Clicked page 2 of blog: No issues.
• Env:
  • Windows 10 + WSL 2
  • php 7.4.3
  • Apache/2.4.41 (Ubuntu)

@pamtbaau
I thank you for going thru all that new installation. My problem is not related to a new installation. My question was how to debug this error. As you can see there is no stack trace and does not pinpoint the problem template page. I am able to route to page 3 with no errors if I type the url in the browser page.

I am evaluating this framework to see if this worth it as a mean to provide to customers. Of course I would love the errors to be more details in case I was to hand off this to a totally new developer.

Anyways, thank you for trying.

Alleluyah, I figured out how to display a full stack trace error on the screen. For those who don't know you can set the error to display the trace by going to the Admin panel > Configuration > Error Handler and set the Display errors to Full Backtrace Error

@codevista,

The plugin currently only processes the page content, not the page header.

The issue is slightly different....

TLDR: Both theme SoraArticle and plugin Youtube use variable youtube in frontmatter/header of a page. But one expects a string value the other an array. If variable youtube is available, always one of the two will fail.

Theme SoraArticle:

• The theme can display a youtube video when the page header provides a url to a video
  YAMLCopy

  ---
  title: Post with YouTube
  date: 19:12 01/04/2014
  youtube: "https://www.youtube.com/embed/e0nnk11KXpQ"
  taxonomy:
    category: blog
    tag: [youtube, video, short]
  ---
  

• Variable youtube is a string containing a url.
• A template in the theme uses {{ page.header.youtube }} to display the video.

Plugin Youtube:

• The Youtube plugin uses the Grav function Plugin::mergeConfig() which merges two arrays: The configuration file of a plugin (e.g. youtube.yaml) and the page's frontmatter variable named after the plugin (youtube). The variable in the header of the page, must thus be an array, like:
  YAMLCopy

  youtube:
  player_parameters:
      autoplay: 1
  

• Variable youtube is an array which can be processed by Plugin::mergeConfig()

Problem:
There is a catch-22 between theme Soraarticle and Youtube plugin: They both use variable youtube but expect different types: string vs array

• The Youtube plugin expects variable youtube to be an array, but a string is given. Hence the error "array_replace_recursive(): Expected parameter 2 to be an array, string given"
• If you fix the variable youtube in the page for the Youtube plugin, the Twig template expecting a variable ({{ page.header.youtube }}) will throw an error: "Array to string conversion"

Solutions:

• Don't use theme SoraArticle in combination with plugin Youtube
• Don't use frontmatter youtube. Which will limit the functionality of theme/plugin.
• Or alter template blog-item.html.twig in theme SoraArticle to use a different variable in the frontmatter of the page.

NB. I've created an issue at theme SoraArticle.
