This is an error in AJV v6
the guys from stoplightio encountered the same problem and solved it
stoplightio/spectral#187 (comment)

I wanted to know if it is possible to add to the dredd a flag that will not validate the scheme, and will only check the response code "--validate-schema" ?
Just like in this library ajv-cli
https://github.com/ajv-validator/ajv-cli#options-1

I can't use dredd because of this bug.

To Reproduce
Use this in your swagger spec:

    "serviceCategory": {
      "type": "object",
      "properties": {
        "id": {
          "type": "integer",
          "format": "int64"
        },
        "name": {
          "type": "string"
        },
        "long_name": {
          "type": "string"
        },
        "parent_id": {
          "type": "integer",
          "format": "int64"
        },
        "type_id": {
          "type": "integer",
          "format": "int64"
        }
      }
    }

    "GetCategoryByIDResponse": {
      "type": "object",
      "properties": {
        "result": {
          "$ref": "#/definitions/serviceCategory"
        }
      }
    }

Expected behavior
No error should be generated or displayed.

What's your dredd --version output?

dredd v13.1.0 (Darwin 19.6.0; x64)

Does dredd --loglevel=debug uncover something?

We found the same issue with the swagger custom format "byte" (dredd v14.0.0 )

Error: unknown format "byte" is used in schema at path "#/properties/content"
    at Object.format [as code] (/..../node_modules/gavel/build/index.js:3:68605)
    at Object.at [as validate] (/..../node_modules/gavel/build/index.js:3:33112)
    at Object.properties [as code] (/..../node_modules/gavel/build/index.js:3:85456)

It seems swagger custom formats (extensions to json-schema) got somehow misconfigured when bumping AJV in gavel.
I'm not sure if this is an issue in Gavel, or the way Dredd uses Gavel. Since both projects are ApiaryIO's I thought it was ok to report it here.

I disagree with the proposed solution of having a flag to skip validation, I would prefer these formats to be supported again.

[abtris]

@artem-zakharchenko do you know if we support this custom data format in schema validation using Gavel?

I think this is pretty much the same as #1719 (comment)
