Ah, sharp! That would be indeed the [“additional added trailing space” bug](https://community.homey.app/t/spatie-achter-variabelen-in-standaard-flows-in-mobiele-app/67169/4) in variables, in the mobile app flow editor…

Check, **in the _web app_ flow editor this works without errors** :

Only _after saving the flow in the web app_, it works in the mobile app:

.  
I just created a ticket @ Athom for this bug.
