It might be worth trying this on Snowplow Micro ( GitHub - snowplow-incubator/snowplow-micro: Standalone application to automate testing of trackers ) first.
At an initial glance my guess would be you’ve changed the metaschema for your schema (to my custom_schema_blob_url). This is a fixed value - so you should leave it as default e.g., your schema becomes:
{
“$schema”: “http://iglucentral.com/schemas/com.snowplowanalytics.self-desc/schema/jsonschema/1-0-0#”,
“self”: {
“vendor”: “com.relevancestudio”,
“name”: “request-event”,
“format”: “jsonschema”,
“version”: “1-0-0”
},
“type”: “object”,
“properties”: {
“endpoint”: {
“type”: “string”
},
“method”: {
“type”: “string”
},
“headers”: {
“type”: “object”
}
},
“required”: [“endpoint”, “method”, “headers”],
“additionalProperties”: true
}
