The FeatureReader for Esri ArcGIS Server Feature Service seems broken in 2024.0. 

I try to read the following feature type : "Zones de gestion intégrée eau par bassin versant - ZGIEBV";

and I get the following error message : ArcGIS Feature Service Reader:

Could not find a layer/table matching feature type 'Zones'

Python Exception <FeatureTypeNotFoundException>: FMEException: 928219: ArcGIS Feature Service Reader: Could not find a layer/table matching feature type 'Zones'

It seems to me like the feature type cannot contain spaces. This worked fine in FME 2023.
