OpenAPI: "request should have required property 'body'" - node.js

Question

I am building out a new endpoint in my application which uses express-openapi-validator as validator middleware.
/* index.ts */
import * as OpenApiValidator from 'express-openapi-validator';
const whitelistedPaths = [/* regex tested paths */];
app.use(
OpenApiValidator.middleware({
apiSpec: './schema/api.json',
validateResponses: true,
ignorePaths: whitelistedPaths,
validateSecurity: true,
}),
);
/* ... */
app.post(
'/users/:email/validateToken',
bodyParser.json(),
(req) => validateToken(req.params.email, req.body.resetToken),
);
In my configuration (api.json) file I've defined the schema for my endpoint as:
"/users/{email}/validateToken": {
"post": {
"tags": ["users"],
"summary": "Validate user token",
"operationId": "validateToken",
"responses": {
"200": {
"description": "Ok",
"content": {
"application/json": {
"schema": {}
}
}
}
},
"parameters": [
{
"name": "email",
"in": "path",
"description": "User email",
"schema": {
"type": "string"
}
}
],
"requestBody": {
"content": {
"application/json": {
"schema": {
"type": "object",
"required": ["resetToken"],
"properties": {
"resetToken": {
"type": "string"
}
}
}
}
}
}
}
},
I've tested with Postman with the following JSON body:
{
"resetToken": "randomd9320ru9"
}
but receive the following error message:
{
"message": "request should have required property 'body'",
"errors": [
{
"path": ".body",
"message": "should have required property 'body'",
"errorCode": "required.openapi.validation"
}
]
}
I'm not sure why it's complaining about the body. I tried putting "required": true under the requestBody config in api.json but that didn't change anything. I just want to make sure that the body includes the required field resetToken.

I suppose you need to use bodyParser.json() before using OpenApiValidator.middleware:
app.use(bodyParser.json());
app.use(
OpenApiValidator.middleware({
apiSpec: './schema/api.json',
validateRequests: true,
validateResponses: true,
ignorePaths: whitelistedPaths,
validateSecurity: true,
}),
);
...
app.post(
'/users/:email/validateToken',
(req) => validateToken(req.params.email, req.body.resetToken),
);
