Ajv is in strictmode

[tganzhorn]

Ajv is in strictmode which makes the usage of validation keywords impossible.

Solution:
Disable strictmode for ajv.

How does it make it impossible? Can you please elaborate a little bit more?

Ok I have to rephrase that. We can’t use user defined keywords. Like for example when I want to use a „visible“ (or any other user defined keyword) keyword on an object for later usage. Ajv throws an error on unknown keywords, and since we don’t have a way to add custom keywords it’s impossible to use that feature. Ajv enabled strict mode in some release I don’t quite remember but there’s a possibility you didn’t catch that change. Greetings from Germany and sorry for my mediocre English 😅

Ok found it: https://ajv.js.org/strict-mode.html#prohibit-ignored-keywords

Wouldn't it be better to support adding custom keywords? Strict mode brings a lot of good. I don't think I want to disable it.

[tganzhorn]

I guess that’s also a possibility, or let the user decide if he wants to disable strict mode completely or wants to add custom keywords.

[tganzhorn]

And yeah strict mode brings a lot of good stuff but sometimes you gotta use them custom keywords 😁

I think we could add a schemaOptions top-level option that accepts a additionalKeywords option.

You can assign this issue to me if you want to. I‘m sure I can add this feature to the codebase.
