found problem, and below is the fix:

This is an issue with SpringBoot, inside our spring project pom.xml

+- <artifactId>spring-boot-starter-parent</artifactId>
|  +- <artifactId>spring-boot-dependencies</artifactId>
|  |  +-  <okhttp3.version>3.14.9</okhttp3.version>

force a compatible okHTTP version in your project by adding the following dependency:

<dependency>
  <groupId>com.squareup.okhttp3</groupId>
  <artifactId>okhttp</artifactId>
  <version>4.9.0</version>
</dependency>
