I had this issue during when I create a custom Rest API in fresh magento 2.4.4p4
As you can see the error I get is Class string does not exist
Below are my code folder structure, which I found to be correct already
app/code/Wowshop/MobileAppApi/
├── Api/
│ └── CustomerInterface.php
├── etc/
│ ├── di.xml
│ ├── webapi.xml
│ └── module.xml
├── Model/
│ └── Customer.php
└── registration.php
Please find below content of the 6 file here

<?php

{
/**

* @param string $password

}

I am unable to figure out how to resolve this isssue, from my checking the docblock I put already correct and same as per the CustomerInterface.php and Customer.php
I have tried changing the @param string $username $password in both file to @param string[] $username $password or @param mixed $username $password but none helps as it gives out other error
If request
* @api
* @param string[] $username
* @param string[] $password
* @return string[]
Error
"The "string" value's type is invalid. The "string[]" type was expected. Verify and try again."
If request
* @api
* @param mixed $username
* @param mixed $password
* @return string
Error
"message": "Class string does not exist",
Please help me understand how this error occur and how to fix this
