Maybe try using only undefined collections, ie with no preset field definitions, to see if that does anything.

Thats why I created an object with a code stage. The Code Stage is working properly and extracts the values in the collection. After that, the object passes the collection to the process. In this step the following error occurs: "The surrogate pair (0xD89A, 0xD89A) is invalid. A high surrogate character (0xD800 - 0xDBFF) must always be paired with a low surrogate character (0xDC00 - 0xDFFF)" So basically, the passing of the collection from object to process studio is not working I think.  The robot is running on a local installation. Database is on the same VDI.  Any suggestions Thank you very much Markus  Thu, 29 Mar 2018 16:35:00 GMT https://community.blueprism.com/t5/Product-Forum/The-surrogate-pair-0xD89A-0xD89A-is-invalid/m-p/47405#M3158 MarkusReich 2018-03-29T16:35:00Z https://community.blueprism.com/t5/Product-Forum/The-surrogate-pair-0xD89A-0xD89A-is-invalid/m-p/47406#M3159 Hi Markus - if you google that error you'll see talk of character sets etc, so I'm wondering if there is some strange character getting into the XML somehow.

I figured out the problem. Somewhere in the extracted csv-file was a ""+"" symbol which caused the error.  Removed the + and everything was running fine.  Cheers Markus  Fri, 06 Apr 2018 14:31:00 GMT https://community.blueprism.com/t5/Product-Forum/The-surrogate-pair-0xD89A-0xD89A-is-invalid/m-p/47407#M3160 MarkusReich 2018-04-06T14:31:00Z
