Console.php array to string conversion notice

With the upgrade to v3.12.0 I’m getting the following error on the settings page:

WARNING: …/core/DataTable/Renderer/Console.php(152): Notice - Array to string conversion - Matomo 3.12.0 - Please report this message in the Matomo forums: (please do a search first as it might have been reported already) (Module: VisitsSummary, Action: getEvolutionGraph, In CLI mode: false)

I have the same issue. Does anyone has a solution?
