Unit tests fail out of the box

[kupietools]

FM Server 19.4.2.204 running on MacOS Catalina 10.15.7 on Intel.

Unit test results:

==========================================
 FILEMAKER API UNIT TEST
==========================================

------------------------------------------
 Test FileMaker object's main methods
------------------------------------------
API version : 2.2.4
Min server version : 10.0.0.0

Get databases list...FMServer_Sample...SUCCESS

Get layouts list...

If I change the error reporting from exception to standard, I get:

Hello,

This sample file requires you to have the filemaker-test.fmp12 file hosted on your local filemaker server. You can find the filemaker-test file in the test folder.
