Elfinder connector return URI for OneDrive gives 404 page not found

[froid24]

I am using this elfinder wrapper in a Laravel 5.7 project. I have configured the OneDrive network mount and the onedrive app with the following return uri:

https://myapp.com/elfinder/connector/netmount/onedrive/1

But when trying to authorise, the return URI called by OneDrive gives a 404 page not found:

https://myapp.com/elfinder/connector/netmount/onedrive/1?code=zzzzzzz-zzzzz-zzzz-zzzz-zzzzzzzzz

Anything other than the following gives a 404 page not found: https://myapp.com/elfinder/connector

This is also the one in the route list of the laravel.

So do I need to do something more? Register the above complete route ( with /netmount/onedrive/1)? It would be expected for the package to do that...

Thanks in advance for the help.

Cheers!
