isNaN under lodash library is used by formioWizard script in ngFormio library which is used by ngFormioBuilder .Recent release of ngFormio using lodash version 4.17.4 ,which is not having isNAN.js ,To avoid this issue please use ngFormio version ,which is using lodash version having isNAN

[CatBakun]

I don't understand what version of ngFormio needs to be used on order to avoid this error. Can you specify?

[anupriyaideas2it]

It is enough to include lodash version in ngFormioBuilder having isNAN.js .Kindly refer lodash releases (for example: 4.17.3)
