-If you are also using Spring Boot, you may run into a common issue where the `OkHttp` version that the Dapr SDK uses conflicts with the one specified in the Spring Boot _Bill of Materials_.
-
-You can fix this by specifying a compatible `OkHttp` version in your project to match the version that the Dapr SDK uses:
