I wish to make Ajv print the piece of my data that is wrong when an error is detected.

I'll make a couple of examples of how Ajv currently behaves and how I wish for it to act:

Example 1

• schema: {const:"hello!"}
• data: "hi"
• error reported by Ajv: data must be equal to constant
• error I wish to see: data ("hi") must be equal to constant ("hello!")

Example 2

• schema: {type:"object", properties:{"x":{}}, additionalProperties:false}
• data: {x:1, y:2}
• error reported by Ajv: data must NOT have additional properties
• error I wish to see: data must NOT have additional properties (found "y")

And so on and so forth. I want more information to help me debug my data for any kind of error, anywhere in the data.

I found lots of information pointing to the ajv-errors package but couldn't figure out how to use it to achieve what I want.

Could anyone suggest if it's possible to achieve what I want and how?
