PHP Fatal error: Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array

This thread is resolved. Here is a description of the problem and solution.

Problem:

The client is unable to open or edit a Spanish page on their site hosted on Pantheon after implementing a fix for a file writing issue. They encounter a PHP fatal error related to 'array_key_exists()' and 'Elementor\Core\Schemes\Color' class not found, along with JavaScript errors in the browser.

Solution:

1. We recommended following the steps outlined in the WPML forum post to address the Elementor integration issue. For more details, visit WPML forum post.

2. We suggested going to WPML->Languages->Hidden Languages to unhide the language and check if the issue persists.

If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem continues, please open a new support ticket at WPML support forum for further assistance.

annaH-23	Background of the issue: I am trying to edit a Spanish page on my site hosted on Pantheon. I have implemented a fix for the 'can't write files' issue, but now I can't open or edit the Spanish page I just made. Symptoms: I am seeing a PHP error: 'PHP Fatal error: Uncaught TypeError: array_key_exists(): Argument #2 ($array) must be of type array'. Additionally, there is a JS error in the browser: 'web-cli.min.js?ver=3.26.1:3 SyntaxError: Unexpected token 'W', "Warning: C"... is not valid JSON'. Questions: Why can't I open or edit the Spanish page I just made? How can I resolve the PHP and JS errors I'm encountering?

annaH-23	The site is already seat to use 256MB. After I switch off all plugins except Elementor/Elementor Pro, including switching off WPML, I can then edit the Spanish version of the Homepage page. Switching WPML back on, results in the page again being uneditable. Deactivating, removing, and reinstalling the WPML plugins, also results in the page being uneditable.
