Hi @BenB
Use javascript Enrichment

{

"schema": "iglu:com.snowplowanalytics.snowplow/javascript_script_config/jsonschema/1-0-0",

"data": {

    "vendor": "custom.co.jp",

    "name": "javascript_enrichment",

    "enabled": true,

    "parameters": {

Hi @Jitender_Attri ,

Sorry for the delay. The vendor and the name should be

		"vendor": "com.snowplowanalytics.snowplow",
		"name": "javascript_script_config",

otherwise, the enrichment configuration is not recognized and is just discarded.

We created this issue to handle that.

@BenB This will give me error
{“schemaKey”:“iglu:com.snowplowanalytics.snowplow/javascript_script_config/jsonschema/1-0-0”,“identifier”:“Javascript enrichment”},“message”:{“error”:“Error compiling JavaScript function: [Cannot invoke “javax.script.Compilable.compile(String)” because the return value of “com.snowplowanalytics.snowplow.enrich.common.enrichments.registry.JavascriptScriptEnrichment.engine()” is null]”}}]},

Hi @Jitender_Attri ,

I tried with your configuration locally and it is working fine.

What is the version of your JDK ?

Javascript enrichment is based on Nashorn engine, which was not available before Java 8.
