Typescript instanceof mongoose.Error

See original GitHub issue

What is the current behavior?

Following the example in https://mongoosejs.com/docs/api/error.html#error_Error

const Model = mongoose.model('Test', new mongoose.Schema({ answer: Number }))
const doc = new Model({ answer: 'not a number' })
const err = doc.validateSync()

err instanceof mongoose.Error // true

I got the error in err instanceof mongoose.Error

namespace Error
The right-hand side of an 'instanceof' expression must be of type 'any' or of a type assignable to the 'Function' interface type.ts(2359)

If the current behavior is a bug, please provide the steps to reproduce.

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that “latest” is not a version.

node 16.14.2 mongoose 6.3.4

It is a documentation error. You have to check against mongoose.Error.ValidationError
