must have required property 'requestBody'

[ilomon10]

i tried to use openapi-backend with express with this setup:

(req: ExpressRequest, res: ExpressResponse, next: NextFunction) => {
   api.handleRequest(
      {
        method: req.method,
        path: req.path,
        query: req.query,
        body: req.body,
        headers: req.headers,
        params: req.params,
      },
      req,
      res,
    );
}

with this schema:

import { Document } from "openapi-backend";

export const apiSchema: Document = {
  openapi: "3.0.1",
  info: {
    title: "REST API",
    version: "1",
  },
  servers: [
    {
      url: "/api/v1",
      description: "API Version 1",
    },
    {
      url: "/api/v2",
      description: "API Version 2",
    },
  ],
  paths: {
    "/attendance/subscribe": {
      post: {
        operationId: "postSubscribeAttendance",
        summary: "Subscribe to attendance",
        requestBody: {
          content: {
            "application/json": {
              schema: {
                type: "object",
                required: ["callbackUrl"],
                properties: {
                  callbackUrl: {
                    type: "string",
                    // format: "url",
                    example: "http://yourserver.com/send/callback/here",
                  },
                },
              },
            },
          },
        },
        responses: {
          "200": {
            description: "ok",
            content: {
              "text/plain": {
                schema: {
                  type: "string",
                },
              },
            },
          },
        },
      },
    },
  },
};

but no luck
