Having this issue when trying to grab the package from an input of which the URL is the PR's original repository.

Configuring npm

ERROR: no dependencies were specified
Hint: set `npmDeps` if using these hooks individually. If this is happening with `buildNpmPackage`, please open an issue.

npmDeps is clearly set in the original derivation's definition, yet it fails to build on my system. Refer to my configuration as to how I'm importing it.
rg with 'llama-swap' should find any relevant bits, if you'd like to help me out.

Ah. llama-swap-149-go-modules.drv. This is probably because I had a cached copy of the go modules beforehand.

Force pushed. If you pull it again it should work this time. Thanks for testing @xNefas :)

Looks like #417516 was working on this but stalled at version 137. (connecting the issues)

Ah, thanks for the link.

Copied locally and swapped to version 150, works for me. 👍
