@tshepangm thanks for the report but we can't really figure out if that is a problem in Spring Boot with the information that you've shared. What is the value for spring.cloud.gateway.routes[0].uri (at line 6 of your application.yaml) for a start?

Please also note that Spring Boot 2.2.x is EOL and you should upgrade to a supported version at your earliest convenience.

I am new on this product,and below is how the application.yaml is configured

        - id: ratelimited_route
          uri: ${RATE_LIMITED_URI}
          predicates:

                rate-limiter: "#{@apiRateLimiter}"
                key-resolver: "#{@apiKeyResolver}"

root@server api-rate-limiter]# locate application.yaml /root/api-rate-limiter/build/resources/main/application.yaml /root/api-rate-limiter/src/main/resources/application.yaml /root/api-rate-limiter/src/test/resources/application.yaml /var/lib/docker/overlay2/e5bf3934e937225e0993ca1127725bd3364bc571dd3ff19fdff738b13fad2273/diff/app/resources/application.yaml [root@server api-rate-limiter]#

Thanks for the follow-up and sorry, I should have paid attention to the error message as the value is already provided. There's no problem that we can fix for you here. ${RATE_LIMITED_URI} hasn't been replaced and this not a valid URI, hence the message that you see. You should make sure that RATE_LIMITED_URI has a value and is a valid URI.
