Spring Cloud Gateway routing doesn't work - spring

Question

I'm using Spring Cloud(Hoxton.SR10) with Spring Boot (2.2.6.RELEASE)
I registre my services in Eureka server 8761
and I have a gateway-service to manage routing (without any security for the moment)
# profil DEV
---
spring:
profiles: dev
cloud:
gateway:
routes:
- id: pr-api-id
uri: http://localhost:8086/
predicates:
- Path=/api/**
and this is the pom.xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-actuator</artifactId>
</dependency>
<!-- Spring cloud eureka client -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
when I call localhost:9092/api/v0 (I have a service on localhost:8086/v0 that working fine) should return me the same result of localhost:8086/v0 du to the routing of spring cloud gateway
but I got http error 404
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
gateway mainClass java

I finally resolve my problem by adding the cors-configuration in my config file.
spring:
cloud:
gateway:
default-filters:
- DedupeResponseHeader=Access-Control-Allow-Origin
globalcors:
cors-configurations:
"[/**]":
allowCredentials: true
allowedOrigins: "*"
allowedHeaders: "Origin, X-Requested-With, Content-Type, Accept, Content-Length, TOKEN, Authorization"
allowedMethods: "GET, POST, PATCH, PUT, DELETE, OPTIONS"
