[Schema Inaccuracy] 500 Error founding in API "/user/emails"

[Nana1209]

Schema Inaccuracy

POST https://api.github.com/user/emails with Authorization and requestBody {"emails":"xxx@xx.com"} will cause a 500 error,
After repeated experiments, 500 errors will be caused when the requestBody is the following structure
{"emails":"xxx"}
This is a server error. Incorrectly formatted input was not processed correctly

Expected

The reponse status should be one of 201,422,304,404,403,401 in reponses

Reproduction Steps

It's not a problem with the schema, but with the API endpoint itself. emails is expected to be an array of strings as per the documentation

But I agree there shouldn't be a 500 response in case emails is set to a string instead, the API should respond with a 4xx error instead, probably a 422

We are doing some research about REST API analysis and testing.
Where should I report error with github API endpoint itself, like 5XX error?

Best to contact support at https://support.github.com/contact, they will forward your request to the right person.

I'll close the issue as there is nothing actionable regarding the OpenAPI spec
