Major Description
In Funding Circle we use avro schema to validate some financial data and we've found ourselves wondering what is invalid. We've noticed that avro does already validation, but does not report what fields are invalid, so we've decided to change it and we use Avro as a validation library.
What error messages to expect?
We communicate errors for a given payload in format "at <path> <expected> <received>".
For <path> we've decided to use syntax similar to json path:
- . refers to root
- [0] first index in array
- .age would match 42 from {"age": 42}
Error within object person and his optional array houses on second item with key number_of_rooms:
at .person.houses[1].number_of_rooms expected type long, got string with value "not valid at all"
Example of multiple errors for a single payload:
at .[0] expected type int, got null
at .[1] expected type int, got string with value \"e\"
