Can anyone help me with how to specify a multi select field in parameters? I have a field that needs to be able to accept multiple values, from what I read online, I need to use a name that ends with '[]', so the field name I was using was "pixel-group[]", but this caused an error as it was a disallowed key, I've now renamed it to :pixel-group and get a new error: clojure.lang.ExceptionInfo: Bad form fields {:status 400, :error {:pixel-group (not (instance? java.lang.String a-clojure.lang.PersistentVector))}} Instead of using 'String' for this field, what should I use?

[String]

@stijn Thanks, it's working now 🙂

you're welcome!
