While Executing karma tasks, I get Script Error

Please see the below.

Running "karma:test.accounting" (karma) task

Below is my karma config file.

parallelOptions: { executors: 2, shardStrategy: 'round-robin' },

When I tried opening up a browser and look for an actual issue, the tests were passing with the below error

Question: Why does it says script error while executing the tests from command line where as it passes the tests while executing in the browser?
