I have a lambda with a Babashka runtime but it’s failing at runtime:

I’d deployed the ARM runtime to my account via this link:

I’m using the HL layer, so it’s strange that the namespace fierycod.holy-lambda.response is reported as something that cannot be found.

Chris Lowe10:06:52

This is using HL 0.6.6 with latest tasks

Karol Wójcik10:06:53

The latest BB runtimes are not shipping HL directly.

Chris Lowe10:06:10

ah, ok

Karol Wójcik10:06:12

You have to include the dependency in bb.edn 🙂

Chris Lowe10:06:17

what do I need to include?

Karol Wójcik10:06:32

HL dependency

Chris Lowe10:06:26

Hmmm - I already have it:

:deps    {org.clojure/clojure                  {:mvn/version "1.11.1"}
           io.github.FieryCod/holy-lambda       {:mvn/version "0.6.6"}
           com.github.clj-easy/graal-build-time {:mvn/version "0.1.4"}}

Chris Lowe10:06:48

I’ll try without the graal-build-time

Chris Lowe10:06:03

I assume Clojure 1.11.1 is ok?

Karol Wójcik10:06:06

Do you have it in bb.edn?

Chris Lowe10:06:57

Nothing explicit for HL in bb.deps

Chris Lowe10:06:26

is there a specific pod I need to add?

Karol Wójcik10:06:27

You need to place io.github.FieryCod/holy-lambda {:mvn/version "0.6.6"} in bb.edn deps
