Error messages might appear when you selectMerge and Boxin Composer.
Error
There was an issue processing the Composer request. The remote server returned an error: (409) Conflict.
Cause
A common reason for these errors is that there are more than 1,000 folders included at any given level of the Composer document output file path. For more information on the output file path, see the OFP parameter.
Composer uses Box's Get Folder Items API call to identify folders where the document is saved. The Get Folder Items API call has a limit of 1,000 folders. Composer is unable to query for folders beyond the limit. For more information on Box, see:https://developer.box.com/reference#...-folders-items
Solution
Add folder levels to your OFP parameter that do not exceed 1,000 folders at any given level in your Box account.
