"Invalid characters in file name!" "errorCode" : 400 - What are the invalid characters.

[andrewsavillkyloepartners]

Using the SDK to upload files to Bullhorn but I was getting this error on file names that seemed to have no invalid characters in them:

"Invalid characters in file name!" "errorCode" : 400

Are you able to supply a list of characters or strings that the back end Rest function is looking for so I can make sure I am checking them on the front end also.

Many thanks,

Andrew
