Hello Negi, Richa,

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

I understand that you are trying to upload a file using blob client and getting an error message.

The error message you’re encountering, “java.lang.NoSuchMethodError: ‘reactor.core.publisher.Mono reactor.core.publisher.Mono.subscriberContext(reactor.util.context.Context)’”, indicates that there’s a compatibility issue between the versions of the Azure Blob Storage SDK and the Reactor library.

Ensure that your Spring Boot version is compatible with the Azure Blob Storage SDK. According to the Spring Versions Mapping, Spring Boot 2.x requires Java 8 as the minimum version, while Spring Boot 3.x requires Java 17 or higher.

refer - https://github.com/Azure/azure-sdk-for-java/wiki/Spring-Versions-Mapping for version compatibility.

Also, you mentioned that you’re using the azure-storage-blob version 12.11.1. However, there might be a mismatch between the Spring Boot version and the Azure SDK version.

Update your pom.xml file to include the correct dependencies for Spring Cloud Azure Storage Blob Starter. refer - https://learn.microsoft.com/en-us/azure/developer/java/spring-framework/configure-spring-boot-starter-java-app-with-azure-storage for more information.
