I am unable to run the default example from the documentation

(defn form []
(rs/with-fsm [state global-image-fsm]
(r/with-let [
text (r/atom "")
update-text #(reset! text (-> % .-target .-value))
]
[:div
[:input {
:type :text
:on-change #(update-text %)
:on-focus #(re-frame/dispatch [::edit-started :validation-open])
:on-blur #(re-frame/dispatch [::edit-ended :validation-open])
}
]
]
)
)
)

I get the below error trace

There is a problem with the with-fsm macro. I have no idea why this error happens. I was able to use the low level api to get it to work but in my own opinion the with-fsm macro looks more high level.

What is missing in the above code ?
