Problem in checkSchema example

[stelasido]

Hi, I am following the example from here: https://express-validator.github.io/docs/schema-validation.html . It is the exact same example, but when I run the app, I am getting a warning in the console:

express-validator: a validator/sanitizer with name isUpperCase does not exist

When I make a request to this route, with invalid data, I am getting this error:

TypeError: chars.replace is not a function

It doesn't matter, if I send or no the username with the request.

Hello!
isUpperCase indeed doesn't exist -- the right validator is isUppercase. I've fixed that and pushed a fix to the docs.

Now on to the TypeError: chars.replace is not a function, this is a problem I couldn't replicate. Are you using which version of express-validator?

Hi, I am using ^6.1.1. Is there a list of the validators, because I can't guess what I need ?
For the example, I am trying with required, isRequired, but it says express-validator: a validator/sanitizer with name isRequired does not exist.

Check this file for validators
https://github.com/express-validator/express-validator/blob/master/src/chain/validators.ts

Check this file for sanitizers

checkSchema({
    parama_name: {
        trim: {
           options: [[" ", "-"]],
        },
    },
 })

Giving me following exception-

chars.replace is not a function

This should work:

checkSchema({
    parama_name: {
        trim: {
           options: " -",
        },
    },
 })
