Which version of PHP are you using here?

This looks like a PHP 8.1 error.

webrees 2.1 does not yet suppor PHP 8.1
I'm waiting for my fix to be accepted by the aura.router project - github.com/auraphp/Aura.Router/pull/176
Once it is accepted, I'll fix the remaining 8.1 compatibility issues.

OK then i got that wrong.
I thought the alpha is already for php 8.0 and later versions.
Will test it with php 8.0.

Thanks

Woody

It works now with PHP 8.0

Thanks

Woody
