Getting type error when accessing errorCode property of a ValidationErrorItem

[shashanksapre]

Describe the bug
Getting a type error when I try to access properties of errors array within an error object of type ValidationError

To Reproduce
Access the property errorCode inside an ValidationErrorItem

Actual behavior
Type error: Property 'errorCode' does not exist on type 'ValidationErrorItem'. Did you mean 'error_code'.
If I try to access error_code, it's undefined.

Expected behavior
Should be able to access errorCode as that's what is returned by express-openapi-validator

Examples and context
I'm trying to transform errors returned by validator into another standard error body response.

I ran into the same issue, looks like the codebase uses a mix of both errorCode and error_code. As a workaround I declared

interface OpenAPIValidationError extends ValidationErrorItem {
    errorCode?: string
}

Using an express middleware I transform them like

const errorCode = err.error_code || err.errorCode || "unknown"
