Uknown error during PowerShell configuration


I try to deploy Matomo on my tenant and add it to my Sharepoint Website.

I use Matomo On Premise Version.

I follow all the step from the readme file. I add Matomo app on my Sharepoint App Library, and I launch script setup.ps1 with PowerShell.

All the step are validated but at the end of the configuration I have the error as you can see in attachment.

Matomo error

Thank you in advance.
