at the end of the nrepl output I see there's a :error-while-loading ch.fabianpage message. if you eval that namespace via the repl do you see any errors?

if there is a compilation error, ideally you'd be getting a stack trace somewhere + a notification in the browser window, so that might need to investigate that

I will try that out later.

But i reproduced the error with a new tutorial project. Will try it out also with an not tutorial project.

hmm, interesting. I just tried starting a new tutorial project (at the moment it should be the same as a non-tutorial project anyway) as a sanity check and I didn't get the error myself. So if you: 1. create a new project 2. run clj -M:dev dev 3. open the signup page at 4. open src/com/example/settings.clj and change "My Application" to something else, then save the file Does the signup page auto-refresh and display the new string? or at least display the new string if you manually refresh the web page?

Hi Jacob, …I did just that on my M1 Mac and it worked fine. I ran your command to create an app; then clj -M:dev dev to start it; browsed to it using Safari; edited the home-pageand saw the expected result in Safari; no errors in terminal/console. Let me know if you want any other detail.

awesome, thanks for checking that.

Thanks, then i know it's my setup

Happy to help debug--hopefully shouldn't be too hard to figure out.

Just to add, my M1 has… $ clj --version Clojure CLI version 1.11.1.1386 $ uname -a Darwin zinc.lan 23.2.0 Darwin Kernel Version 23.2.0: Wed Nov 15 21:53:34 PST 2023; root:xnu-10002.61.3~2/RELEASE_ARM64_T8103 arm64

I changed the logging level by adding

that is bizarre... this is the line that breaks: https://github.com/jacobobryant/biff/blob/93baa98ff714d2bc29715ab746f6aa7ce5751ec0/src/com/biffweb/impl/misc.clj#L29 the :now gets converted to (java.util.Date.). it appears that either that or #inst "1970" is ending up as a symbol instead of an inst. can you eval (inst-ms #inst "1970") in the repl?

I wonder if you have something funky going on with data readers.

it also might not hurt to try another jdk version just in case? technically 19 is unsupported by clojure I believe since it's not an LTS release; you could try 17 or 21 instead... though ideally we can at least reproduce the symbol-instead-of-inst behavior without switching jdks.

( …My M1 Mac is using 17 )

; eval (root-form): (inst-ms #inst "1970")
; (err) Execution error (IllegalArgumentException) at repl/eval53833 (REPL:87).
; (err) No implementation of method: :inst-ms* of protocol: #'clojure.core/Inst found for class: clojure.lang.Symbol

That only hapens in the nrepl connected from nvim.

if i just start clj then i get back 0.

So i have a problem with my nrepl config

the plot thickens! does switching jdks make a difference? what do you get from evaling (identity #inst "1970")? as a workaround it wouldn't hurt to use a modified version of use-beholder that initializes last-called to (java.util.Date.) instead of #inst "1970". I'll make that change in the next release, and in the mean time you can copy-paste use-beholder into your project and make the changes there. I'm interested to see if any other errors come up. also you could try creating a miniminal example of the bug--E.g. create a new project with only nrepl as a dependency, start an nrepl server, see if you get the error. etc.

Interestingly removing (:gen-class) fixed this problem.

I will try to investigate furter on monday to find the root problem

very interesting. I'll try to do some fiddling sometime too.

(jdk 21)

Same experience here, fresh starter project, - Arch Linux

$ clj --version
Clojure CLI version 1.11.2.1446
$ java --version
openjdk 22 2024-03-19
OpenJDK Runtime Environment (build 22+36)
OpenJDK 64-Bit Server VM (build 22+36, mixed mode, sharing)

Nothing in ~/.clojure/deps.edn except for a few aliases that I wasn't using. Just did clj -M:dev dev

are you able to reproduce the error after deleting .m2?

maybe there's some set of libraries that conflict and cause the error some how... like two libraries with the same namespace or something?

if you do manage to get back in the broken state, do you get this behavior as well? https://clojurians.slack.com/archives/C013Y4VG20J/p1708722054768849?thread_ts=1708614733.658089&cid=C013Y4VG20J

Everything is well after removing ~/.m2. Should probably have saved the bad state somewhere.

If it happens again, I'll make sure to back it up 👍

Sounds good!
