video of Stuart Halloway's TriClojure talk introducing Datomic Ions https://www.youtube.com/watch?v=3BRO-Xb32Ic

I'm following the cloud tutorial https://docs.datomic.com/cloud/setting-up.html

and I've gotten all the way to the part where you try to connect to aws from the repl

but this is what I get

user=> (def client (d/client cfg))
ExceptionInfo Unable to connect to system: #:cognitect.anomalies{:category :cognitect.anomalies/not-found, :message ": Name or service not known"}  clojure.core/ex-info (core.clj:4739)

I ran the socks proxy script and it says that my endpoint to the bastion is good

my endpoint key in the cfg map looks exactly like it does in the cloudformation console

Your :system-name and :query-group values in the cfg map are both gdeer81?

I don’t know that this would cause that problem, that’s just how I have my working REPL/socks setup set up

question about Ions: if I run say items-by-type out of ion-starter at the REPL I get a nice pretty string with an array of arrays in it, suitable for such activities as deserializing into JSON

when I invoke that ion as a Lambda, however, I get a nice pretty string that is the first string wrapped in a hashset (e.g., "#{[[...stuff...]]}")

This presents a problem if I want to then deserialize the result of a Lambda execution somewhere. Is that extra #{...} wrapper Lambda the Ultimate’s doing? Is there a way to “turn it off”?

(apologies if this is answered in the video above, which I haven’t gotten a chance to watch. Stupid linear time!)

didn't realize you were asking me if the sys name and query were the same, thought you were asking me why

Right, which is gdeer81

then I realized I haven't posted the config map

{:server-type :ion,
 :region "us-west-2",
 :system "gdeer81",
 :query-group "gdeer81",
 :endpoint ""}

the helpful Slack message is coming from inside the house! 😄

Can you run the aws cli command shown in the docs that lists system names

aws ec2 describe-instances --filters "Name=tag-key,Values=datomic:tx-group" "Name=instance-state-name,Values=running" --query 'Reservations[].Instances[].[Tags[?Key==`datomic:system`].Value]' --output text

aws ec2 describe-instances --filters "Name=tag-key,Values=datomic:tx-group" "Name=instance-state-name,Values=running" --query 'Reservations[*].Instances[*].[Tags[?Key==datomic:system`].Value]' --output text`

gary@pop-os:~/Downloads$ aws ec2 describe-instances --filters "Name=tag-key,Values=datomic:tx-group" "Name=instance-state-name,Values=running" --query 'Reservations[*].Instances[*].[Tags[?Key==`datomic:system`].Value]' --output text
gdeer81

Hmm
