update item via URL path (I would like to update an item in the same library as the running workflow)

I used the following target url: https://fagg-afmpstest.govshare.fed.be/sites/digipro/DMSQuality/00QualityDEV/File%20SOP%20CCC%20-%20Copy%20(10)/ANNEX 
→ It is a link to a folder in the same library (and it works when i past this in my browser).. I’m always getting the same error An error occurred in WorkflowDMSQuality_DEV
