Trying to implement azure ke vault in spring boot application application run successfully but if i try to fetch the secrets from vault using get request then getting error

If I use spring boot 3.0.5 then getting below error but if i run it in spring boot 3.2.3 then running fine for running in spring boot 3.0.5 i need to add these dependencies

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-security-keyvault-secrets</artifactId>
    <version>4.7.3</version>
</dependency>

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-identity</artifactId>
    <version>1.11.1</version>
</dependency>

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-handler</artifactId>
    <version>4.1.101.Final</version>
</dependency>

If i don't add dependency of netty handler then project doesn't run getiing below error

But I want to access azure key vault in spring 3.0.5 because our enterprise project is created in spring 3.0.5
I can't understand the issue.
Is it because of spring version or any other issue kindly response accordingly

I attached the actual pom of our project
