[Vuejs]-Vee Validate custom cross-field rule, comparing two time strings

So! the problem was that my events on the Vee Validate was set to “” and after I set it to "blur" the validation triggered.
Although the error was coming from error.first('symbol_input) which according to my errorBagName should have been vErrors.first('symbol_input').
If anybody gets stuck on this like me maybe this answer will be where they went wrong.
