ArcGIS 10.5 FME Data Interoperability ArcGIS Online reader not working

Just upgraded from ArcGIS 10.3.1 to 10.5 and now Data Interop will not read any AGO data. This goes for tools made in 10.3.1 and new tools started from scratch in 10.5. Below is the log. The problem is at Python Exception : global name 'resp' is not defined

The same error comes up whether I am trying to run an old tool with the reader already on the workbench or when I try to add the reader in a new tool.

This is on windows 7 64 bit. I did not uninstall any old ArcGIS software.

Answer

I'm told this is a known issue and that, happily, a patched file has been made available and is easy to install.

For ArcGIS Desktop 10.5 Data Interoperability, the fix is simply to copy the patched file (arcgisonlineCommon.pyc) to C:\Program Files (x86)\Esri\Data Interoperability (x86)\python\python27\arcgisonline\

Obviously that will require Administrative permissions to do, but then the AGOL format should work fine.

I've got a copy of the file and made it available on DropBox.

Esri are aware of the issue and have a copy of the file so it should be in future updates/installers. But I don't know if their support team has a copy, so if the Dropbox link doesn't work, contact Safe Software for the file.
