Answer 1

The issue has been resolved by just replacing the below dependency
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
instead of
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>

Answer 2

Didn't fully understand the issue, but can help with what we were doing to fetch config from a config server for a certain microservice.
as in your case, users microservice will have a dependency like this in pom.xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
And project will have a file called bootstrap.yml or bootstrap.properties as below
spring:
application:
name: user-service
cloud:
config:
uri: <config-server-url>
username: <if-exists>
password: <if-exists>
hope this will be helpful to resolve your issue.

Answer 3

but it seems there is an issue with "name": "https://github.com/balanjaneyulu23/PhotoAppConfiguration/file:C:\Users\admin\AppData\Local\Temp\config-repo-8473851427074645327\application.properties"

Answer 4

In your app.properties or JAVA_OPTS end your path with / such that its not read as a file
-Dspring.config.location=/app/etc/

Answer 5

As you can see i got same error.
In maven panel its clearly shows that main reason of error is dependency. You have to import correct version of dependencies.
First thing you have to do is make sure that your config server is up.
For example you have xxx-dev.yml in your config file. You have to access this config file with http://localhost:8888/xxx/dev. (in this example config server process on port 8888)
If your config server up then you should check your dependencies & properties file in your project which will use config server.
Your project application.properties file
# APPLICATION NAME
spring.application.name=xxx
# PROFILE
spring.profiles.active=dev
# CONFIG SERVER
spring.config.import=optional:configserver:http://localhost:8888
Your project pom.xml file
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
Do not forget the add spring-cloud.version property into the pom.xml file. It will help you to import correct version of config client.
...
<properties>
<java.version>17</java.version>
<spring-cloud.version>2022.0.0</spring-cloud.version>
</properties>
...
After correcting the dependency it will be work fine.
