Summary

• Convert nested Map/ConfigMap values to the declared Record subclass when resolving CLI dot-notation parameters
• Fixes two related bugs that surface when a params entry or a process input is typed as a custom Record (e.g. Sample) and supplied via dot notation
• Follow-up to Fix destructured record input in module run #7164, which fixed the same scenario for destructured tuple-record inputs

Problem

Given a module test/records with a typed record input:

nextflow.enable.types = true

record Sample {
    id: String
    greeting: String
}

process RECORDS {
    input:
    sample: Sample

    script:
    """
    echo "$sample.id $sample.greeting"
    """
}

and a workflow module.nf as the following:

nextflow.enable.types = true
include { RECORDS; Sample } from "test/records"

params {
  sample:Sample
}

workflow {

    inputs = channel.of(
        params.sample
    )

    RECORDS(inputs)
}

Running with dot-notation CLI parameters fails:

1. nextflow run module.nf --sample.id a --sample.greeting hola

   Parameter `sample` with type Sample cannot be assigned to [id:a, greeting:hola] [RecordMap]
   

   The params DSL converts the nested map into a RecordMap (via TypeHelper.asType) but the subsequent assignability check rejects it.

2. nextflow module run test/records --sample.id a --sample.greeting hola

   WARN: [RECORDS] invalid argument type at index 0 -- expected a Sample but got a ConfigMap
   

   The process entry handler passes the nested ConfigMap straight through without converting it to the declared Record type.

PR #7164 fixed the equivalent case for destructured tuple-record inputs; this PR extends the fix to named record inputs.

Changes

• ParamsDsl.isAssignableFrom treats RecordMap as assignable to any Record subclass.
• ProcessEntryHandler.getValueForInputV2 converts a Map value into the declared record type via TypeHelper.asRecordType when the input type is a Record.

Test plan

• ParamsDslTest — record param resolved from a nested map
• ProcessEntryHandlerTest — dot-notation params for named record input
• ProcessEntryHandlerTest — ConfigMap value for named record input (module run path)
• Manual: nextflow run module.nf --sample.id a --sample.greeting hola
• Manual: nextflow module run <module> --sample.id a --sample.greeting hola
