Failed to load external schema from reference #855
Description
Using 1.0.86 version of validator
So, I have a json schema, and I want to describe the "seoData" object from this schema in a separate schema file (SeoDataSchema.json), that is placed in a "commonSchemaTemplates" folder on the same level as main schema
Main schema:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {
"header": {
"type": "object",
"properties": {
"requestId": {
"type": "string"
},
"version": {
"type": "string"
},
"serverTime": {
"type": "string"
},
"versionApi": {
"type": "string"
},
"viewType": {
"type": "string"
},
"sourceUid": {
"type": "string"
}
},
"additionalProperties": false,
"required": [
"requestId",
"version",
"serverTime",
"versionApi",
"viewType"
]
},
"seoData": {
"$ref": "file://./commonSchemaTemplates/SeoDataSchema.json#/definitions/seo"
}
},
"additionalProperties": false,
"required": [
"header"
]
}
And SeoDataSchema.json:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"additionalProperties": false,
"definitions": {
"seo": {
"type": "object",
"properties": {
"metaTitle": {
"type": "string"
},
"info": {
"type": "string"
},
"metaDescriptionq": {
"type": "string"
}
},
"additionalProperties": false,
"required": [
"metaDescriptionq"
]
}
}
}
When I'm trying to validate a json file against the main schema, I'm receiving the following error from networknt json schema validator:
Failed to load json schema!

Also, I've tried to specify reference like this:
"seoData": {
"$ref": "./commonSchemaTemplates/SeoDataSchema.json#/definitions/seo"
}
In this case, I have a following error:
Caused by: com.networknt.schema.JsonSchemaException: #/properties/seoData/$ref: Reference ./commonSchemaTemplates/SeoDataSchema.json#/definitions/seo cannot be resolved
at com.networknt.schema.RefValidator.
I figured out the only way to make it work is to specify absolute (full) path to external schema, which is not really good approach
What could be wrong ?
May'be I'm incorrectly specifying the relative path to external schema ?
