Validate the operation documents against the schema

[ardatan]

We can use validate as it is but we need to consider the custom validation rules etc that user might be using.

Right now if the document has a field that is not available in the schema. They get the following error;

💥 🕸️  Mesh TypeError: Cannot read properties of undefined (reading 'name')
