Generating new JSON schema from previous JSON schema after jsonschema validation errors

Currently I have a JSON Schema. I am validating it with document.json (which is a json document and contains real data). I am doing the validation with the help of "jsonschema" package in node.js. After the validation, I want to create new JSON Schema which will contain the previous JSON Schema and the attributes that were in document.json but were not present in original JSON Schema.Currently what I do is look for validation errors after I validate the json schema and document.json and based on those validation errors I create new JSON Schema.

My Question is that, if there is some package which can help me automatically create new json schema based on validation errors?

Thanks in advance!
