Trying to access array offset on value of type int wp-includes/formatting.php on line 884

I'm using WordPress 5.7.2 with PHP8.0, GCS plugin and Divi theme builder.
And this is my log when importing divi layout json pack:

Hi @kientv,

Welcome to Trac!

Even though the error specifically references a WordPress Core file, this issue is usually caused by a non-array value being passed to a function or filter. This issue will need to be reported to the plugin or theme responsible for the feature you were attempting to use.

I'm closing this as invalid, but only because there is nothing actionable on the WordPress Core side right now and that is the default ticket resolution.
