TS2339:Property 'checkBody' does not exist on type 'Request'.

[veerandev]

Using v3.2.0 in typescript, getting TS2339:Property 'checkBody' does not exist on type 'Request'.
As of v3.1.0, the type definitions are shipped with the library. What else could cause this issue?

public add(req: express.Request, res: express.Response, next: express.NextFunction) {
    ...
     if(req.checkBody('name', 'Invalid name').isValidInput()){
       
        ...
     }

public add(req: any, res: express.Response, next: express.NextFunction) {
...
if(req.checkBody('name', 'Invalid name').isValidInput()){

    ...
 }

Have you uninstalled old typings from DefinitelyTyped? If you have both you're likely to get conflicts.

Also, try v3.2.1, as it ships with lots of typings improvements.

EDIT:

This solution solved all my problems

I'm having this same issue. I uninstalled @types/express-validator and don't have any other type definitions in my project, but keep getting errors about many of the validator properties not existing on the Request type. I'm running version 3.2.1 on a Mac, if that helps any.

I applied the middleware in my main Api.ts file with all my other middleware, so the types should be available throughout my program, right? I get the intellisense and autocompletion when I begin typing req. but when I try to run my mocha tests, which are also .ts files, that's when I'm getting the typescript compilation errors.
