If any users, that have created analysis files in the Library that contain scripts or data functions, have been deleted from the user directory, running the find-analysis-scripts command can result in errors like the following:

File 'somefilename' (b806a4b3-f1d8-4a24-b81f-d36162610e28) analyzed, 0 scripts, data functions and custom queries found
Writing a report to: /opt/tibco/tss/10.3.0/tomcat/spotfire-bin/find-analysis-scripts/report_2019-05-07.csv
The 'guid' argument must not be null.

In the server.log, you will see an error similar to this:
