By the way, I updated WPML to the latest version few days ago, and Translation Basket started to show the error message below.
Fatal error: Uncaught TypeError: Argument 1 passed to Types_Post_Builder::set_wp_post() must be an instance of WP_Post, null given, called in /var/www/html/SITE_NAME/wp-content/plugins/types/application/models/field/group/repeatable/wpml/translation_job_data.php on line 52 and defined in /var/www/html/SITE_NAME/wp-content/plugins/types/application/models/post/builder.php:19 Stack trace: #0 /var/www/html/SITE_NAME/wp-content/plugins/types/application/models/field/group/repeatable/wpml/translation_job_data.php(52): Types_Post_Builder->set_wp_post(NULL) #1 /var/www/html/SITE_NAME/wp-content/plugins/types/application/controllers/m2m.php(108): Types_Field_Group_Repeatable_Wpml_Translation_Job_Data->wpml_tm_translation_job_data(Array, NULL, Object(Types_Post_Builder), Object(WPML_Translation_Job_Helper)) #2 /var/www/html/SITE_NAME/wp-includes/plugin.php(235): Types_M2M->{closure}(Array, NULL) #3 /var/www/html/SITE_NAME/wp-content/plugins/wpml-translation-management/classes/translation-jobs/class-wpml-element-translation-p in /var/www/html/SITE_NAME/wp-content/plugins/types/application/models/post/builder.php on line 19
Additionally, to which WPML version you try to update from what version. Could you please share these details and I will try to check reproduce this issue on my install. Few screenshot of "Translation Basket " would be helpful.
