Machine Learning Extractor - proxy authentication issue

We currently use the enterprise version of UiPath studio and just installed the 2019.8 preview as we want to try out some of the document extraction capabilities.

Have noticed the following issues:

  1. When attempting to use the Machine Learning Extractor, am getting a proxy authentication issue. Our IT department enforces a proxy, I tried entering it in the ‘UiPath.Service.Host.exe.config’ file but it seems to not be considered when running this activity. Is there anyway around this?

  2. Our use case involves reading data from Vendor Quote PDF’s which is deemed too sensitive to upload into the cloud for processing. Is there any plan to release on-prem support for the processing of invoice/receipt models? If so, when?

Appreciate any response.
