Unmapping File Content
When you setup Data Synchronization tasks to download from Dropbox to your local system or to upload files from your local system to Dropbox, you must unmap the file content on the Field Mapping tab. If you do not unmap the file content, the Data Synchronization task cannot run as expected, an invalid data type conversion error appears.
1. In Field Mapping Tab, select FileContent field.
2. Click 
(clear expression/lookup) to unmap the FileContent.
