Compatibility with WPML?

I am trying to implement an advanced search on a wp website.
Website has these characteristics:
– Multilanguage (WPML)
– with custom post types (CPT UI)
– with custom fields and taxonomies (ACF)
– with tags and categories

Search (WP Extended Search) is performed on:
– tags
– categories
– ACFs

I expected to see: the search results, available for the selected/current language

Instead, I got: SQL error and no results.
You can find the debug.log here:https://gist.github.com/totanus/2b053022c6e662167f0184d36e8fe7f8

If I disable WP Extended Search, the search works BUT not on ACF or Tags, of course.
If I disable WPML, the search works BUT of course, the website is not multilingual ??
