another error on update customer data

[winnie80]

Description
UvDesk API bundle tickets filtration use actAsType="customer" and actAsEmail="email.address" as main identification
This resulting our customers losing their ticketing after they change their email address.
So I tried to submit email change using route /api/v1/customers/update/{customerId}
But I got the following error message returned

{
    "status": false,
    "message": "Class \"Webkul\\UVDesk\\ApiBundle\\API\\UserPasswordEncoderInterface\" does not exist"
}

How to reproduce
As example I used customerId 8
Use this route /api/v1/customers/update/8
Use method POST (this route will not work using PUT)
Send in JSON format data that I want to changed, in this case the email address, for example

{
    "email": "new.user.email.address@outlook.com"
}
