anyOf returns repeated errors

What version of Ajv are you using? Does the issue happen if you use the latest version?

"ajv": "^8.11.0",
"ajv-formats": "^2.1.1",

Ajv options object

I am using Ajv with allErrors option, a few keywords and formats as well

const ajv = new Ajv({allErrors: true})
const formats: FormatName[] = ['date']
this.validator = addFormats(ajv, formats).addKeyword('kind').addKeyword('modifier')

JSON Schema

My schema is being generated through another package called typebox. This is what the schema looks like when it’s passed to Ajv for the validation.

{
  kind: Symbol(ObjectKind),
  type: 'object',
  properties: {
    enumProperty: {
      kind: Symbol(EnumKind),
      anyOf: [Array],
      modifier: Symbol(OptionalModifier)
    }
  }
}

Sample data

{
  "enumProperty": "invalid-value"
}

Your code

Not relevant at this point, I think.

Validation result, data AFTER validation, error messages

"data/enumProperty must be equal to constant, data/enumProperty must be equal to constant, data/enumProperty must be equal to constant, data/enumProperty must be equal to constant, data/enumProperty must be equal to constant, data/enumProperty must be equal to constant, data/enumProperty must match a schema in anyOf"

What results did you expect?

I would like to have a simple message indicating that the value is not valid for the schema and the acceptable values for that property:

"data/enumProperty must match a schema in anyOf: ["value1", "value2"]"

If that’s not possible, than just the first part would suffice:

"data/enumProperty must match a schema in anyOf"

Are you going to resolve the issue?

Unlikely

@felixjb Refer to comment https://github.com/sinclairzx81/typebox/issues/174#issuecomment-1134944761 for reasoning behind TypeBox’s preference for anyOf over enum.

Thank you so much!
