:io.pedestal.http.secure-headers/secure-headers - Key must be integer

I'm having this error, what does it mean?

you need a full stack trace

*e

but, what that's trying to tell you is that there is a call to assoc to a vector, and you can only assoc to integer keys in the vector

but your code has passed that keyword instead

(assoc [:foo :bar :baz] :quux 42) instead of (assoc [:foo :bar :baz] 0 42)

thanks 🙂

the stacktrace couldn't be found in *e @ghadi
