Question: validation errors

[betzerra]

Hi! I'm trying to build a custom error middleware and I noticed that I'm getting some validation errors squashed into one item.

I got:

[
  "#: missing properties: \"foo\", \"bar\""
]

while I was expecting:

[
  "missing property: \"foo\"",
  "missing property:\"bar\""
]

when calling Fields(). Is that something I could easily override or setup?

hi, the error messages are not necessarily combined or separated by property, they are created with the context of particular validation check (mostly constraint keyword and related parts of value)

here is how this particular error is created: https://github.com/santhosh-tekuri/jsonschema/blob/v3.1.0/schema.go#L298

        if len(s.Required) > 0 {
            var missing []string
            for _, pname := range s.Required {
                if _, ok := v[pname]; !ok {
                    missing = append(missing, strconv.Quote(pname))
                }
            }
            if len(missing) > 0 {
                errors = append(errors, validationError("required", "missing properties: %s", strings.Join(missing, ", ")))
            }
        }

It seems there is no easy way to customize that.
