getEvolutionGraph not available in On-Premise installation

[coemans-com]

The ChatGPT plugin can't return any insight because 'getEvolutionGraph' is not available. I installed the plugin on Matomo 5.1.1.

Error message:
The given JSON data does not contain any significant metrics to provide insights from. However, it indicates an error notification. The error message signifies that a method named 'getEvolutionGraph' does not exist or is not available in the specified module - '\Piwik\Plugins\VisitsSummary\API'. Thus, the key insights are that your software is experiencing an error due to missing or inaccessible method in the specific module, which needs to be addressed for normal functioning.
