Json schema not validating as expected - json

Question

I am working on a Json schema for validation but it does not seem to be working.
Apart from the if then condition, the rest works fine but even though i am following the example provided in jsonschema - Applying Subschemas Conditionally, it does not work.
This is the schema
'''

and this is what i am trying to validate
''' {
"$schema": "./blank.json",
"answers":[ {

"question": {
"key": "hello",
"type": "rating"
},
"value": 1234

Okay... I see the problem.
Here's the if subschema that you expect to trigger for your data
{
"properties": {
"question": { "const": "rating" }
}
}
However, in your data, question has a type property.
"question": {
"key": "hello",
"type": "rating"
}
This means that the if subschema isn't passing because {"key": "hello", "type": "rating" } != "rating".
You'll need to update your if subschema to account for this property hierarchy.
{
"properties": {
"question": {
"properties": {
"type": { "const": "rating" }
}
}
}
}
You'll need to do this for all of the if subschemas.
Making just this change gives this error on my validator:
{
"valid": false,
"keywordLocation": "#/properties/answers/$ref/items/allOf/0/then/properties/value/maximum",
"absoluteKeywordLocation": "https://json-everything/base#/definitions/question_type/items/allOf/0/then/properties/value/maximum",
"instanceLocation": "#/answers/0/value",
"error": "1234 is greater than or equal to 5"
}
