Node catalog Scripts

Run custom R code

Usage and specifics

Source can be inline, Git or a workspace. Code runs through the container runtime on the selected target. The image, dependencies and repository access must be available on that target.

Technical type : script_r. Runtime : docker.

Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the credentials guide if a remote source or execution target requires access.

Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

Configuration help

image Container image: Image used to run the script (e.g. docker.io/library/node:22-bookworm). Use localhost/name:tag for a local Podman image.
secretCredentialIds Secrets: Secrets connections injected as environment variables of the script (process.env, os.environ...). The file carrying them is deleted as soon as the container starts.

Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
