Unknwon route Error in Spring cloud Gateway

[Junnyjun]

Describe the bug

When I use spring cloud gateway, I get unknown route in fleet.

Steps to reproduce

1. This is the gradle I used

plugins {
	id 'org.springframework.boot' version '3.1.5'
	id 'io.spring.dependency-management' version '1.1.3'
	id 'org.jetbrains.kotlin.jvm' version '1.8.22'
	id 'org.jetbrains.kotlin.plugin.spring' version '1.8.22'
}

group = 'com.test'
version = '0.0.1'

java {
	sourceCompatibility = '17'
}

jar {
	enabled = false
}

repositories {
	mavenCentral()
}

springBoot {
	buildInfo()
}

ext {
	set('springCloudVersion', "2022.0.4")
}

dependencies {
	implementation 'org.jetbrains.kotlin:kotlin-reflect'
	implementation 'org.springframework.boot:spring-boot-starter-actuator'
	implementation 'org.springframework.cloud:spring-cloud-starter-gateway'
	implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
	implementation 'org.springframework.cloud:spring-cloud-starter-circuitbreaker-reactor-resilience4j'

	implementation 'org.springframework.cloud:spring-cloud-starter-config'
	implementation 'io.opentelemetry:opentelemetry-api:1.31.0'
	testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

dependencyManagement {
	imports {
		mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
	}
}

tasks.withType(KotlinCompile) {
	kotlinOptions {
		freeCompilerArgs += '-Xjsr305=strict'
		jvmTarget = '17'
	}
}

tasks.named('test') {
	useJUnitPlatform()
}

2. My apm version -> elastic-apm-agent-1.43.0.jar
3. execute script is

/boin/JAVA17 -javaagent:/elastic-apm.jar -Delastic.apm.service_name=gateway-servicemesh -Delastic.apm.server_url=http://localhost:8200 -Delastic.apm.environment=dev -Delastic.apm.application_packages=gateway -jar -Dspring.profiles.active=dev my-app.jar

Expected behavior

Occurred when calling a service after connecting a gateway, service to eureka.

Hi @Junnyjun ,
Solution from link provided above contains solution for your case - try to use https://www.elastic.co/guide/en/apm/agent/java/current/config-http.html#config-use-path-as-transaction-name configuration.
I tested it locally with same spring-boot and cloud versions.
