Fellow Coders,
kind of stuck on this error.
Attaching the application code and stack trace


.

Are the tokens and user/password combinations left in the application.yml file on purpose?
Seems like not the way to do this to be honest.

I'm getting this error while starting data loader application , done all the config mentioned in video no 7 - https://www.youtube.com/watch?v=7I37-awpaGg , but still getting this error.

complete stack trace -

Hello @koushikkothagal, I hope you're doing well. I tried running your repo, and I'm getting the following error:

Exception in thread "main" java.lang.IllegalStateException: Invalid bundle: missing file config.json
at com.datastax.oss.driver.internal.core.config.cloud.CloudConfigFactory.createCloudConfig(CloudConfigFactory.java:114)
at com.datastax.oss.driver.api.core.session.SessionBuilder.buildDefaultSessionAsync(SessionBuilder.java:876)
at com.datastax.oss.driver.api.core.session.SessionBuilder.buildAsync(SessionBuilder.java:817)
at com.datastax.oss.driver.api.core.session.SessionBuilder.build(SessionBuilder.java:835)
at com.telusko.AstraJavaDemo.ConnectDatabase.main(ConnectDatabase.java:16)

I also followed the exact same documentation given in the DataStax website, but I couldn't resolve the issue. Any ideas what could cause this problem?

hI, i've followed this tutorial exactly as it has been shown and when I run my application on minute 26 it fails to run. I've got a few issues:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.data.cassandra.CassandraDataAutoConfiguration'

Suppressed: com.datastax.oss.driver.api.core.auth.AuthenticationException: Authentication error on node

any idea why this is happening?

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
٢٠٢٢-٠٧-٠٤ ١٩:١٠:١٥.٨١٥ ERROR 12676 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter :

APPLICATION FAILED TO START

Description:

The dependencies of some of the beans in the application context form a cycle:

┌─────┐
| betterReadDataLoaderApplication (field io.betterRead.author.AuthorRepository io.betterRead.BetterReadDataLoaderApplication.authorRepository)
↑ ↓
| authorRepository defined in io.betterRead.author.AuthorRepository defined in @EnableCassandraRepositories declared on CassandraRepositoriesRegistrar.EnableCassandraRepositoriesConfiguration
↑ ↓
| org.springframework.boot.autoconfigure.data.cassandra.CassandraDataAutoConfiguration
↑ ↓
| cassandraSession defined in class path resource [org/springframework/boot/autoconfigure/cassandra/CassandraAutoConfiguration.class]
↑ ↓
| cassandraSessionBuilder defined in class path resource [org/springframework/boot/autoconfigure/cassandra/CassandraAutoConfiguration.class]
└─────┘

Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.
