I am totally confused by a cljdoc problem I have encountered.
Presenting problem:
All of my cljdoc local trial runs, as well as cljdoc-analyzer runs, yield:
"Cannot invoke \"clojure.lang.IFn.invoke(Object, Object)\" because the return value of \"clojure.lang.Var.getRawRoot()\" is null"
It appears to successfully analyze the clj code, but fail on doing the cljs analysis (entire output available later):
Analyzing for clj

⏱ Analysis for clj took: 1.803s

stderr:
{:clojure.main/message
"Execution error (NullPointerException) at sci.impl.copy-vars/var-meta (copy_vars.cljc:65).\nCannot invoke \"clojure.lang.IFn.invoke(Object, Object)\" because the return value of \"clojure.lang.Var.getRawRoot()\" is null\n",
Background:
I routinely run cljdoc locally to ensure that my docs will work with cljdoc when I push them to GitHub. This generally works fine, and for instance I successfully ran cljdoc locally on zprint 1.2.7 prior to releasing it. It worked locally. And, indeed, when I pushed 1.2.7, cljdoc successfully analyzed my code and docs and you can see the docs for zprint 1.2.7 work fine online with cljdoc today.
I have been doing the same thing while working on zprint 1.2.8, and it was working fine. I last had it work on Sept 1. On Sept 9, I was unable to get the analysis of the code to work (received the above error), no matter what I tried. I tried a newer version of cljdoc locally, no luck. I had done very little to the code in the intervening period, so I was quite surprised. I tried a lot to things, all to no avail.
I then tried to work with older jar files, thinking I had messed something up. Still, the same problem.
I cloned the 1.2.7 version off of GitHub into a new directory, and tried that. Same problem.
I then looked at cljdoc issues. Nothing obvious. I stumbled into cljdoc-analyzer. Maybe this would help, or give better errors, or something?
For what it is worth, I'm running on macOS on MacBook Air M1, using:
clone/zprint % sdk use java 17.0.5-oracle
Using java version 17.0.5-oracle in this shell.
I installed it locally:
√ clone/zprint % clojure -Ttools install io.github.cljdoc/cljdoc-analyzer '{:git/tag "RELEASE"}' :as cljdoc
...
cljdoc: Installed io.github.cljdoc/cljdoc-analyzer RELEASE
Then I built the jar in the cloned version of zprint, 1.2.7, with
and ran the analyzer on it:

and I get the same problem. When I look at my local cljdoc output for zprint 1.2.7, I see:
[API import failed in build #47](http://localhost:8000/builds/47)
but when I look at the "real" cljdoc online, for zprint 1.2.7, I see that it works fine.
I've attached the file log.txt which contains the entirety of the output from the above command: log.txt.
I am totally confused by this problem, and have no idea what could be wrong. Given that I successfully analyzed zprint 1.2.7 with my local copy of cljdoc running (where I run the sever locally), and now cannot successfully analyze that same code, I'm at a loss as to what could be the problem. I had upgraded babashka along the way, but tried downgrading it to a previous version -- no change.
I've probably done something that is causing this, but I have absolutely no idea what it could be. Any help would be appreciated.
Thanks!
