Script Sample 'Get Store Product Data' won't work?

Hi,

I tried the script sample 'Get Store Product Data' (http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/metadata/get_store_product_data/start) but won't get any reasonable result. The only responseData I received is '"{\"error\":\"OK (7991690983107231706)\"}".

If I try the url within firefox (e.g. https://www.daz3d.com/dazApi/slab/22740) I'll get the full response with a lot of data.

How can I keep the script running?
