while searching for a function in the repo using SPC-s-f in spacemacs it gave error as,

  Hide: Clojure Java REPL Tooling Duplicates  (42 frames hidden)

  This is an unexpected CIDER middleware error.
  Please submit a bug report via `M-x cider-report-bug`.

  If these stacktraces are occurring frequently, consider using the
  button(s) below to suppress these types of errors for the duration of
  your current CIDER session. The stacktrace buffer will still be
  generated, but it will "pop under" your current buffer instead of
  "popping over". The button toggles this behavior.

Thanks for the report!

Can you give one or a few examples of an input that would cause this?

If you try out cider-20211002.1153.tar (i.e. today's CIDER snapshot published on MELPA) it should work
