Hello,

After successfully using ions for over a year I’ve started getting the following error today while trying to push

{:command-failed “{:op :push}”,  
:causes  
({:message  
“class java.lang.String cannot be cast to class java.io.File (java.lang.String and java.io.File are in module java.base of loader ‘bootstrap’)”,  
:class ClassCastException})}

I’ve reverted my commits to a working deployment, but no luck. I’ve also downloaded the starter project and same error. Any suggestions on where to look. I don’t see reference in code-deploy. Thanks for any help you can provide.

Local clojure deps issue. reinstalled clojure and updated local projects deps and worked fine.
