A/B testing plugin ERROR

Good afternoon!

We have Matomo deployed, we have installed the A/B testing plugin. We have encountered the following problem:
When creating a test, an error occurs: “Key “forward_all_query_params” for sequence/mapping with keys “idexperiment, idsite, confidence_threshold, mde_relative, name, description, hypothesis, included_targets, excluded_targets, success_metrics, percentage_participants, original_redirect_url, status, start_date, modified_date, end_date, forward_utm_params, variations, start_date_site_timezone, end_date_site_timezone, date_range_string, duration” does not exist. ”

Do the AB tests automatically work when the base script is installed or do I need to install additional code? Embed code does not give JS tracker

Hi @Noskova
As this concerns A/B testing premium plugin, I suggest you reach directly the Matomo support team:
