To view where the okhttp dependency is coming from please run the below command this will display the dependency in a tree format

mvn dependency:tree

Once you figure out where the dependency is populated from, you can exclude(How to exclude dependency in a Maven plugin?) okhttp from there, and add your required version.

okio version used is 1.13 .The version required for the okhttp 4.9.1 is higher. Okhttp will bring the dependency as transitive dependency of okio .
