JSON::Validator.validate throws TypeError exception class/object expected

[chibeepatag]

I'm using ruby 2.7.1 and rails 6.1
When validating the following json against the following schema, JSON::Validator.validate throws TypeError exception class/object
JSON:
[ { "name": "enable_customer_membership", "value": null }, { "name": "time_zone", "value": "Guam" }, { "name": "company_name", "value": "Demeter Trading Inc." }, ]

Schema:
{
"id": "https://celine.com/v1/setting.schema.json",
"title" : "Setting",
"type": "array",
"items": {
"type": "object",
"properties": {
"name": {
"type": "string",
"description": "name of setting"
},
"value": {
"anyOf": [
{ "type": "number" },
{ "type": "null" },
{ "type": "string" },
{ "type": "integer" },
{ "type": "boolean" }
]
}
},
"required": [ "name", "value" ]
}
}

We encountered this today in our project -- it seems closely connected to a change in Spring, from v4.0.0 to v4.1.1: rails/spring@21e272f. Is it possible you have a new version of Spring, and is it possible that downgrading will "resolve" this bug? If so, then it's a bug on Spring...

am facing this issue as well. downgrading to 4.1.0 works. not sure how spring is causing validate! to fail...
