Running provisioning fails. Error "Illegal Characters in path" (100750)

There appears to be a rule that is causing an error in Quick Connect provisioning workflow.
When the details are checked the following error occurs: "Illegal Characters in path".

When a rule is created with a combination of text (e.g. path name) and attributes, the entire string has been entered in a text string and not recognised as a combination of text and attribute.

When creating the rule, click the drop down button next to "Attribute", select "Rule..."
For the text, enter the strings in as text. For attributes in the string, enter as attribute and select the attribute.

e.g. for a rule:

c:\newids\%<sAMAccountName>.id => LNIDFile.

Follow this procedure:

Click configure next to "Configured generation rule"

Click "Add", "Text", Enter the path of the location.
Click "OK"
Click "Add", "attribute", "Select"
Choose "First Name", Click "OK", OK".
Click "Add", "attribute", "Select"
Choose "Last name", Click "OK", OK".
Click "Add", "Text", Enter the file extension ".id"
Click "OK", "OK".
