AJV: no schema with key or ref "https://json-schema.org/draft-07/schema"

I am using ajv 8.6.2

I have schemas that validate against draft-07 using the default export

When I use the draft-09 export all of my schemas give me this error:

no schema with key or ref "https://json-schema.org/draft-07/schema"

Same error exists if I use this:

no schema with key or ref "https://json-schema.org/draft-09/schema"

Can't seem to figure out what's going on here?

Solution

  • If you mean by

    When I use the draft-09 export all

    that you're using Ajv2019 instance

    import Ajv2019 from "ajv/dist/2019"
const ajv = new Ajv2019()

    then you need to add the draft-07 metaschema:

    const draft7MetaSchema = require("ajv/dist/refs/json-schema-draft-07.json")
ajv.addMetaSchema(draft7MetaSchema)

    as explained at https://ajv.js.org/guide/schema-language.html#draft-2019-09-and-draft-2020-12

    FYI, don't refer to JSON meta schemas with https://, their identifiers do start with http://, ajv doesn't retrieve them, it packages them instead.
