With the help of networknt json-schema-validator i’m trying to validate json schema. The below code is working fine in Android 11

    val mapper = ObjectMapper(YAMLFactory())
    val jsonNodeReader = JsonNodeReader.builder().yamlMapper(mapper).build()
    val factory = JsonSchemaFactory.getInstance(SpecVersion.VersionFlag.V4) {
        it.jsonNodeReader(jsonNodeReader).build()
    }
    val config = SchemaValidatorsConfig.builder().build()
    val schema = factory.getSchema(schemaFile, InputFormat.YAML, config)
    val messages = schema.validate(yamlFile, InputFormat.YAML, Consumer { it.executionConfig.formatAssertionsEnabled = true })

but it doesn’t work in Android 5.1. I’m getting the below error

Uncaught Exception in Thread ID: 1 - Thread name: main
