Uncaught in promise TypeError Cannot use in operator to search for __vInternal i

This error occurs when the in operator is used to search for the property __vInternal in a JavaScript Promise object, but the property is not found.

The __vInternal property is an internal property used by some libraries or frameworks, such as Mongoose, to store internal state or metadata. It is not a standard JavaScript property.

To fix this error, you need to identify where the in operator is used to search for __vInternal and either remove or modify the code to handle the property correctly.

If you are using Mongoose, make sure you are not trying to access or manipulate the __vInternal property directly. Instead, use the provided Mongoose methods and properties to interact with your data.

If you provide more context or code related to the error, I can provide a more specific solution
