Test does not recognise processor resource from template

[gorun2git]

Redpanda Connect versions: 4.57.1 and 4.65.0

I'm trying to create a processor template that includes multiple custom steps (processors).

Here is my config:

The template file

type: processor
name: custom_sub_pipeline
fields:
  - name: mapping
    type: bloblang

mapping: |
  root = {
    "processors": [
      { "resource": "pre_custom_mapping" },
      { "mapping": "" + this.mapping },
      { "resource": "post_custom_mapping" }
    ]
  }
  
tests:
  - name: the basic processor template
    config:
      mapping: |
        this.blah = blah.blah
    expected:
      processors:
        - resource: pre_custom_mapping
        - mapping: "this.blah = blah.blah\n"
        - resource: post_custom_mapping

How I'm trying to use template:

input:
  label: input_kafka_template
  kafka:
    topic: ${USER}.test.raw

output:
  label: output_kafka_template
  kafka_out:
    topic: ${USER}.test.trans

pipeline:
  processors:
    - custom_sub_pipeline:
        mapping: |
          import "./transformations/test.blobl"

          let data = this.apply("test_mapping")
          root = {
            "data": $data
          }

Running test with:
redpanda-connect test --templates './templates/*.yaml' --resources './resources/*.yaml' './tests/test.yaml'

With the mentioned config, the lint is passing successfully, but redpanda-connect test is failing with failed to initialise processor index '0': processor type of 'custom_sub_pipeline' was not recognised

Note: Might be duplicate with #194
