I also explored down this path, with no clarity yet: https://clojurians.slack.com/archives/C68M60S4F/p1646737904726649?thread_ts=1646732244.136159&cid=C68M60S4F

hello, the problem is the position of the params, in this example the params is set at the ident level, and params don't flow down (they are only acessible at the place they were defined)

this is the query to send the params at the right place in your case:

(def eql-with-params
  ['{[:asset/id 13]
     [(:asset.series/level
        {:time.series/from #inst "2021-12-11T00:00:00.000-00:00",
         :time.series/to   #inst "2021-12-16T00:00:00.000-00:00"})]}])

Ah. Fulcro generates it like I have it: https://clojurians.slack.com/archives/C68M60S4F/p1646732244136159?thread_ts=1646732244.136159&cid=C68M60S4F Is there something obvious I'm missing?

this issue is about a conceptually mismatch in this case, for Fulcro it thinks the params are "entity level", but for Pathom the params are "per attribute", the common solution in Fulcro with Pathom 2 is to use Pathom plugin that forwards down the params from a parent entity via environment

another thing I believe (have to test) you can do is to put the param strait in the query, instead of using the fulcro :params thing

the plugin solution doesn't exist afaik for Pathom 3 yet
