Thanks @lee - I solved it! It was a misunderstanding on my part, I thought the analysis failure was from cljdoc-analyzer but it was actually from the cljs compiler's analyzer. I didn't have a cljs version set in the project and cljdoc used an older version of cljs. After I specified the latest cljs in deps.edn things worked 🙂
Great to hear @danvingo, thanks for following up and sharing your success! The analyzer should probably default to a newer version of cljs... maybe.
