[Vuejs]-I have an error with otp component in vuetify in vue

its because of your vuetify version (vuetify version must be 2.6.0 or higher)

for updating vuetify:

1.Run npm info vuetify to lookup for the list of versions that they have.

npm info vuetify

2.install the specific version that you want with the following
for example:

npm install --save vuetify@2.6.6
