on error transition not invoked

[nyemiks]

I have a state machine defined as follows

logInFsm { :id :login-service :http-xhrio { :uri "http://127.0.0.1:8081/crm/api/user-profiles/authenticate" :method :post :params credentials :format (ajax/json-request-format) :response-format (ajax/json-response-format {:keywords? true})
:headers { "userId" "csduser1" "tenantId" "test" "provider" "test" } } :max-retries 5

        :on-success    [::myevent/response "success"]
        :on-error        [::myevent/error-response "error"]
        :on-failure      [::myevent/fail-response "failure"]
        }

The state machine is started as follows

(rf/dispatch [::http/start logInFsm])

When testing, I noticed that if there is an error from the server, the configured on error event is not invoked.

Here is the error log

It appears there is an uncaught exception which is occuring in the re-statecharts.core library.

I am still new to clojure so I am not at the level where I can make adjustments to underlying libraries.
