[Zoo-discuss] Reg: Exception in DescribeProcess request

Mon Aug 1 23:59:50 PDT 2016

Dear Anju,
it is very strange that the zcm contains none, it should contain the mimeType returned by the request used to access the InputPolygon reference.

So it means something went wrong when downloading the ressource.

You may try to run the execute request from the command line and see if any more information are displayed there, you can refer to this part of the documentation [1].

Also, note that you should remove the zcm and zca files when they are empty or contains none. In other case the ZOO-Kernel will always use this local copy as the value for the input, so your request will always failed.

I hope it helps and we can get more info by running from the command line.

Best regards,

This directory should be created or the line defining the cacheDir should be removed from your local main.cfg. I have also noticed that this directory is not created by the installer, so this have to be fixed directly in the installer also.
