Better error messaging for NOT

[mikethecalamity]

What version of Ajv you are you using? 8.11.0

What problem do you want to solve? I have a schema with a not clause which, on failure, returns a very unhelpful/confusing message: my-schema.json/thing must NOT be valid

"thing": {
    "type": "number",
    "not": {
        "exclusiveMinimum": -0.25,
        "exclusiveMaximum": 0.25
    }
}

What do you think is the correct solution to problem? I think the correct messaging would be something along the line of what it would say if the criteria was not wrapped in a not. Something like:

my-schema.json/thing must NOT be < 0.25, my-schema.json/thing must NOT be > -0.25

Will you be able to implement it? Unsure

What you are effectively asking is converting schema to English. That is certainly out of scope for Ajv. In general, such negative rules are better avoided in schemas - it makes it non-declarative. You may also consider using JTD.

You can also try ajv-errors that allows you to supply your own errors.
