Use params in custom errors about ajv-errors

[epoberezkin]

it's not supported at the moment, can be added. Not sure about the syntax though, need to think about it.

It would be really amazing as it would allow to have really clear error messages on fail just with the path and the error message without any additional processing.
It would be even better if we could also inject the error path in some way.

What about a callback with everything we could need as argument ? (But I guess it'll not work because it's supposed to be a JSON schema, right?)

errorMessage: {
    additionalProperties: (path, params) => `Invalid property ${params.additionalProperty} at path ${path}`
}

Or maybe a new kind of tokens likes $${params.additionalProperty} or ${{params.additionalProperty}} ?

This would be very helpful, especially when validating enums since the default messages just say "should be equal to one of the allowed values" without specifying the allowed values.

Hey! Any update about this feature? :)

I would like something to this effect. Basically, I want both the error message and error code to be included. I tried attaching objects (and hacking around meta-schema), but that only led to an endless loop. And that jst definition file is totally opaque for me... :(

Hope to see any progress!

In my case I used the {0#} to get the additional property that it is added
