Wrong number of args (0) passed to: clojure.core/max

[tgk]

I attempted to use clofidence to generate a test report for our internal API using the README as a guide. After using the configuration from the README and running $ clj -X:test:clofidence the test suite runs just fine but when it comes to generating the report it errs:

{:clojure.main/message

Can you share your deps.edn alias with the config? I have seen that once when nothing gets instrumented because some issue in the instrumentation config.

@jpmonettas of course! Sorry for the delay:

Seeing this and your comment made me realize it's probably the "-XX:-OmitStackTraceInFastThrow" 🤔 Thanks!

[tgk]

Ah, also I just copied the pattern for what should be instrumented. Sorry, obviously that's the problem.

[tgk]

That solved it! Sorry for the noise. It might be nice to have better error reporting for my (admittedly stupid) mistake.

[jpmonettas]

Great to hear it is solved! Yeah I agree that error is very confusing for a common mistake like wrong instrumentation. I'll leave this open and something for it!
