TJ's ZWDA_701_ACF_UPDOWNLOAD error 262

Hi all,

I implemented Thomas Jung's 'ZWDA_701_ACF_UPDOWNLOAD' component as described in: https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/109b9b52-bc00-2c10-8786-e4c5e96d7e04

But I get following error when trying to upload the files:

This seems to be a problem with the whitelist. (Websearch for this error doesn't give any idea.)

I created the whitelist as described in the video and downloaded it.

Anyone any idea what I've possibly done wrong?

BR
