Validation problems when json object uses decimals

[luismiguelcelda]

I'm encountering a validation issue when validating an JSON object with draft-06 version of schema:

Schema:

{ "$schema": "http://json-schema.org/draft-06/schema#", "title": "RemoteStartTransactionRequest", "type": "object", "properties": { "connectorId": { "type": "integer" }, "idTag": { "type": "string", "maxLength": 20 }, "chargingProfile": { "type": "object", "properties": { "chargingProfileId": { "type": "integer" }, "transactionId": { "type": "integer" }, "stackLevel": { "type": "integer" }, "chargingProfilePurpose": { "type": "string", "additionalProperties": false, "enum": [ "ChargePointMaxProfile", "TxDefaultProfile", "TxProfile" ] }, "chargingProfileKind": { "type": "string", "additionalProperties": false, "enum": [ "Absolute", "Recurring", "Relative" ] }, "recurrencyKind": { "type": "string", "additionalProperties": false, "enum": [ "Daily", "Weekly" ] }, "validFrom": { "type": "string", "format": "date-time" }, "validTo": { "type": "string", "format": "date-time" }, "chargingSchedule": { "type": "object", "properties": { "duration": { "type": "integer" }, "startSchedule": { "type": "string", "format": "date-time" }, "chargingRateUnit": { "type": "string", "additionalProperties": false, "enum": [ "A", "W" ] }, "chargingSchedulePeriod": { "type": "array", "items": { "type": "object", "properties": { "startPeriod": { "type": "integer" }, "limit": { "type": "number", "multipleOf": 0.1 }, "numberPhases": { "type": "integer" } }, "additionalProperties": false, "required": [ "startPeriod", "limit" ] } }, "minChargingRate": { "type": "number", "multipleOf": 0.1 } }, "additionalProperties": false, "required": [ "chargingRateUnit", "chargingSchedulePeriod" ] } }, "additionalProperties": false, "required": [ "chargingProfileId", "stackLevel", "chargingProfilePurpose", "chargingProfileKind", "chargingSchedule" ] } }, "additionalProperties": false, "required": [ "idTag" ], "$id": "urn:OCPP:1.6:2019:12:RemoteStartTransactionRequest" }

JSON object to validate:

{ "connectorId": -36350181, "idTag": "et id nisi", "chargingProfile": { "chargingProfileId": 97423894, "transactionId": 5413440, "stackLevel": 56179684, "chargingProfilePurpose": "ChargePointMaxProfile", "chargingProfileKind": "Absolute", "recurrencyKind": "Daily", "validFrom": "1952-03-23T13:27:11.0Z", "validTo": "1969-06-02T18:20:55.0Z", "chargingSchedule": { "startSchedule": "1929-07-17T08:05:06.0Z", "chargingRateUnit": "W", "chargingSchedulePeriod": [ { "startPeriod": -33003912, "limit": -1294569.8, "numberPhases": -80998804 }, { "startPeriod": 32382491, "limit": -1382612.3 } ], "minChargingRate": -37064270.9 } } }
Received error:
{ instancePath: '/chargingProfile/chargingSchedule/chargingSchedulePeriod/0/limit', schemaPath: '#/properties/chargingProfile/properties/chargingSchedule/properties/chargingSchedulePeriod/items/properties/limit/multipleOf', keyword: 'multipleOf', params: { multipleOf: 0.1 }, message: 'must be multiple of 0.1' }

I attempted to validate the same data using multiple online JSON Schema validators, and all of them reported NO errors.
