I have installed Ipgramatech wishlist API, it's working but https://baseurl/swagger is giving me this error message.

Hello @asimbyazid 

If you are miss matching parameters data type in DocBlock annotation of either interface or model you can face this error "Class “array” does not exist"

OR

If you are passing wrong parameter's data type in postman or API call you will face this 'Class “array” does not exist issue.
