"No reader function for tag object" when formatting EDN buffer

[orestis]

I have an EDN buffer which is huge long line and I'd like to pretty-print it with indentation etc.

I tried cider-format-edn-buffer and got this Exception {:type :reader-exception, :ex-kind :reader-error}. This probably because the EDN looks like:

#object[next.jdbc.connection$url_PLUS_etc$reify__28723 0x14570829 "jdbc:postgresql://my-database.com:5432/"]

I would expect though that the formatter wouldn't care to actually read the EDN (it could pass through any unknown tags, right?)

Cider version is 0.24.0

Thanks!

The code in question is:

cider-nrepl/src/cider/nrepl/middleware/format.clj

Lines 48 to 56 in 2587706

	(defn- format-edn
	[edn print-fn]
	(->> (read-edn edn)
	(map (fn [value]
	(let [writer (StringWriter.)]
	(print-fn value writer)
	(str writer))))
	(str/join "\n")
	(str/trim)))

Maybe the #object tag handler can be temporarily bound?
