main test passes without errors.

send attemp : value passed - always different 28 or 32 or 36

Time: 835ms Passed: 33Failed: 10 Errors: 1Exit Code: 10

TypeError: Cannot read property 'length' of null
at getLengthOfMissingArray (test.js:4:9)
at Context. (test.js:38:24)
at processImmediate (internal/timers.js:464:21)

what could be the reason for the test or my code ?

javaScript .
thanks.

I have already found a solution.

I only fail Fixed Tests where I can see Fixed Tests.
Input Validation Tests -> true
Random Tests -> true

I don't understand what this error means

Basic tests
Test Passed: Value == 'TestCase'
Test Passed: Value == 'CamelCaseMethod'

TypeError: Cannot read property 'toLocaleUpperCase' of undefined
