Error says duplicates on data/required but none found

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

Your code

var ajv = new Ajv({allErrors: true, jsonPointers: true});
        // ajv.addMetaSchema()
        var schema = state.schema.validation
        var data = state.output

        const isValid = ajv.validate(schema, data); //schema, data
        if(! isValid){
          // console.log('%c ***** VALIDATION DETAILS *****','color:pink')
          // console.log("NOT VALID ",ajv.errors);
          state.valid = false;
          state.errors = ajv.errors;
        }else {
          // console.log('%c ***** VALIDATION RESULT *****','color:limegreen')
          // console.log(isValid)
          state.valid = true;
          state.errors = []
        }

Validation result, data AFTER validation, error messages

Uncaught Error: schema is invalid: data/required should NOT have duplicate items (items ## 10 and 6 are identical)

What results did you expect? I don't see any duplicates on required or on the data being validated so I would expect it to validate

Are you going to resolve the issue? I've tried adding older meta schemas with addMetaSchema but with no luck. I need help

[epoberezkin]

Please reduce the example to the minimal size when it is still failing and post the failing code sample to runkit.com - it’s not clear what is what in the provided code.

[epoberezkin]

It does look like the schema above and the one that is passed to Ajv are different

[marcodarko]

Hi, thank you I created this but this works. https://runkit.com/marcodarko/avj-schema-validator-test. However I'm not using node so I can't get the same error I see on my inspector console.

[marcodarko]

I'm sorry I updated the schema on this issue and the runkit version should be accurate too, I included the whole thing by accident but updated it to the part that avj receives. is the CDN version not up to date maybe? idk

[epoberezkin]

Try reproducing it in a single script in the browser without dependencies - same script that works in runkit should work in the browser. There is nothing browser specific, unless you have some old browser.

Looking at the error, the schema above and what is passed to Ajv is not the same - so the problem might be in your code.

I’m going to close this issue - re-submit as browser / compatibility if these suggestions won’t help.

[epoberezkin]

Also please use schema under say 20 lines - most issue usually can be reproduced with this size.

[marcodarko]

Just FYI I was able to reproduce the same error here : https://runkit.com/marcodarko/avj-schema-validator-test

[epoberezkin]

“Required” on line 551 has a duplicate item “identifier”.
