💻 Code

class Bug {
  
    /**
     * @param {some-module.Request} request
     */
    sendRequest(request: unknown): void {
        arguments; // Remove this, error goes away
    }

}

🙁 Actual behavior

An error occurs in the type of the @param jsdoc tag: Cannot find name 'some'.

🙂 Expected behavior

No error occurs on the @param jsdoc tag

Notes

This only happens if arguments is referenced in the body of the method.

This behavior was introduced in #47257 (ping @a-tarasyuk )

The issue seems to be that if arguments is referenced then getTypeFromTypeNode(lastJSDocParam.typeExpression.type) (Line) is invoked to see if the the last parameter is an array type. The problem is getTypeFromTypeNode will add the diagnostics about being unable to find some even though in this context we probably don't want to add it.
