Cannot set the error for a type of array

[shuowpro]

Problem:

I tried with a schema like this

var schema = {
  "type": "array",
  "items": {
    "type": "object",
    "properties": {
      "foo": { "type": "string" },
      "bar": { "type": "number", "maximum": 3 }
    }
  }
};

This is an array schema, I cannot get the error when I want to valid the properties inside the object of the array such as foo or bar.
I don't know whether that is a bug. I try to validate that with ajv, and the ajv reported 2 errors with dataPath: [0].foo and [0].bar, the first character of the dataPath is not ., so that I think that might the reason why the buildSyncValidate will not transform the dataPath into the format like /0/foo, so that I cannot validate the field in a object in the array.

I think the if statement of detect whether the first character of dataPath is . or not is redundant. This will be repaired by remove that if statement.

I've encountered the same error. From what I've managed to see it is the bug in the deepmerge library.

I have data structure like follows:

{
    list: [{ foo: 'val', bar: 'val' }, ...]
}

The bug happens in following code:

// buildSyncValidation.js
    var errors = ajvErrors.map(function (error) {
      return setError(error, schema);
    });
    // We need at least two elements
    errors.push({});
    errors.push({});
    return _deepmerge2.default.all(errors);

The ajvErrors.map will return something like this

[
   { list: [ {foo: 'some error} ] },
   { list: [ {bar: 'some error} ] },
]

_deepmerge2.default.all(errors) then returns following

{ list: [  {foo: 'some error}, {bar: 'some error} }

which is not correct.
I believe this bug was fixed in version 2 of the deepmerge library. Maybe only updating that package would fix this. Disregard this, just saw "deepmerge": "^2.0.1", in package.json.

@br0wn Hello, have you found any solution for that? I found a temporary solution for this. I can read the schema and build a field level validation manually. But I don't think this is a good solution for now.

@leuction Unfortunately no :( I disabled the default sync validation provided by the library as I don't need it at the moment. If you have time and will, you can fix buildSyncValidation.js and provide a PR :) Until it is merged you can use your fork.
