Environment

[X] Office 365 / SharePoint Online [ ] SharePoint 2016 [ ] SharePoint 2013

If SharePoint on-premises, what's exact CU version:

Expected or Desired Behavior

docSet.CreateFolder(folderName) should create a folder within the custom Document Set even if a column in the SharedFieldCollection contains a space in field name.

Observed Behavior

This error occurs when the Library contains a custom Document Set Content type where one or more columns in the SharedFieldCollection contains space (X000) in the internal name.

We found a work-around as long as the custom Document Set Content type is defined at the site collection level. If defined in Content Type Hub the work-around does not work even if we un-publish the content type.

• The work-around is described in the StackOverflow thread mentioned below.
• The source code used to observe the problem is described in the StackOverflow thread mentioned below.
