Exception - Call to undefined function get_mimetypes_array()

We recently received the following error when attempting to open two different student submissions in a class assignment.  The student submissions that were uploaded were MS Word documents (.docx format).  The other Word documents that were uploaded to the assignment do not have this problem.  Has anyone experienced this problem before, or have any insight on how fix it?  Our current environment is: 

Moodle 3.4.2, MS Windows Server 2016, SQL Server 2014, PHP 7.1

The full developer debug error we receive is:

Exception - Call to undefined function get_mimetypes_array()

Debug info:
Error code: generalexceptionmessage

I believe we have found the cause of the issue.  This seems to occur when the document's file name is more than 90 characters, including spaces and the file extension.  Files with 90 characters work properly, but those with 91 characters do not.  I've created MDL-62324 to report this issue as a bug.

Thanks
