We run a self-hosted Matomo 5.2.2 on a VPS. Right now, the following message appears in our Matomo dashboard:
“WARNING: /plugins/Events/VisitorDetails.php(63): Warning - Trying to access array offset on value of type null - Matomo 5.2.2”
The site in question has not been officially launched yet, meaning there is very little data for it in the DB.
I can just click away the message and go on with my work, but it’s still a bit annoying.
