Azure Deployment Failing with HttpServerErrorException for my Spring App

Question

Trying to deploy my Java SpringBoot app on Azure with Azure Spring Apps. I have set config server to pick up yml file from a git repo. I don't think it locates it either.

Below are some of the logs:

2023-12-21T10:16:54.8424399Z Some error occured during deployment. Printing latest app instance log:

I have tried upgrading and downgrading spring cloud version (using spring-cloud-verion 2022.0.3). I have tried switch config repo branches. I still think I'm missing something.

Java applications are generally the most difficult ones to launch on Azure, depending on the packages or other factors.

• Please check the below configuration of my pom.xml file:

<plugin>
        <groupId>com.microsoft.azure</groupId>
        <artifactId>azure-spring-apps-maven-plugin</artifactId>
        <version>1.17.0</version>
        <configuration>
                    
            <subscriptionId>Azure_SUbscription_id</subscriptionId>
            <resourceGroup>Resource_group_name</resourceGroup>
            <clusterName>kpspringapp</clusterName>
            <appName>springboot-crud</appName>
            <isPublic>false</isPublic>
            <deployment>

                          <filtering/>
                          <mergeId/>
                          <targetPath/>
                        <directory>${project.basedir}/target</directory>
                          <includes>
                               <include>*.jar</include>
                          </includes>
                       </resource>
                   </resources>
              </deployment>
         </configuration>
    </plugin>

Go to the root folder of the spring-boot app and run the below commands.

• mvn clean install
