Dash Schema validation has a standardized format for reporting the results of Schema instance validation and any errors occurring within that validation.
{
valid: { boolean }
errCode: { number } Error code
errMsg: { string } Error message
objData: { object } The object being validated
objType: { string } Name of the object subschema
rootSchema: { object } Definition of the root Schema used to validate this object
}
The error object always exists, either as an empty object {} or a ValidationObject. Therefore it is not sufficient to check for the existance of the
errorobject in a ValidationResult. Instead, positive confirmation must be obtained by checking that the.validproperty === true, to avoid situations where a bug returned null from some validation code.
