Brother I am getting this exception: " The URI scheme of endpointOverride must not be null.". Is there any solution or suggestion for it?

You could try "https://s3.wasabisys.com" rather than "s3.wasabisys.com" as the service endpoint. When constructing an URI, you need to define the protocol aswell.

Thank for your response. But now getting this error
java.lang.VerifyError: Verifier rejected class software.amazon.awssdk.http.apache.ApacheHttpClient: void software.amazon.awssdk.http.apache.ApacheHttpClient.lambda$LRMaF_8eLuzzpRjS-Ew4gJswCBw(org.apache.http.client.methods.HttpRequestBase) failed to verify: void software.amazon.awssdk.http.apache.ApacheHttpClient.lambda$LRMaF_8eLuzzpRjS-Ew4gJswCBw(org.apache.http.client.methods.HttpRequestBase)

Can you tell me what is the reason of this error? I searched for the error but didn't get any idea. It will be a great pleasure for me if you tell me what is the reason.

Maybe this helps: https://wasabi-support.zendesk.com/hc/en-us/articles/360021962192-How-do-I-use-AWS-SDK-for-Java-v2-with-Wasabi-

Thanks a lot.
