503 SERVICE_UNAVAILABLE "Provider error"

Getting 503 Service_unavailable error when I’m executing python command on the second terminal to start the dashboard application. All Maven repository files are created and in place, and the server is starting properly but not be able to figure out where is the problem.

Please help @Saurav_Crio.Do @gouravsardana

Take a look at this link:

It seems like server issue.

Hey @visargdesai, thanks for reply.
I known what it means but not be able to troubleshoot. My test cases are passing before execution/ start of server. But when I run my application it just throwing this error as response. :sweat_smile: If you known something about this and how to troubleshoot this please give me some hints.

What I know is 503 comes from server when there is high traffic on the server and it is down because of that. It not be able to provide further services. But why I’m getting this in localhost it is a mystery for me as well :sweat_smile::joy:.

Is there an IllegalArgumentException ?
java.lang.IllegalArgumentException: Expected scheme-specific part at index 6: https:

@akashchhetri

Yes, and also getting errors in file present in annualreturn->src->main->java->com->crio->stock->annualreturn app and file is showing 41 errors this is cloned file :frowning:

I think this problem arising because I missed importing jar files.

This is a Gradle project so there is build.gradle file for getting dependencies. Use build.gradle if you missed any dependencies. But I think the exception is due to improper URI parsing. I am also getting the same exception.
And those 46 errors would be the exception propogated through method calls.

Yes, I also put the dependencies in place after executing python file this error propagates.

You can take a look at the console of the ./gradlew bootrun to check what kind of exceptions are being logged. That will give you an idea of what could be going wrong…

Usually in real world, whenever any cowerker want to report an exception in your code, they will come along with the stack-trace that they see in the console. so its good to start with that.
Let me know if the stacktracke is not helpful, we will see what else we can do

@anand-crio I ran ./gradlew bootrun command and after reading stack trace the exception I’m getting is this

java.lang.IllegalArgumentException: Expected scheme-specific part at index 6: https:
at java.net.URI.create(URI.java:852)

facing same issue but different errors

unable to connect now

@akashchhetriwhere do you see this exception? Do you have complete sack trace of your gradle bootrun?

@aungrah Can you give me full stack trace?

@anand-crio
Thanks for help!! I resolved It !
There was mistake in URL Builder.

why start the Spring Boot application take too much time ??
er28

It is server actually so it will keep running!

but , is it running correctly ??
