Validation using records is not working

Bug report

Expected behavior and actual behavior

When using records with types , the values should be validated with their respective record type

Steps to reproduce the problem

Using this minimal example:

nextflow.enable.types = true

record Sample {
    id: Boolean
    path: Path
}

process hello{
  input:
  sample: Sample
  script:
    """
    echo "Hello sample ${sample.id}!" >>output.txt
    echo "sample.id class = ${sample.id?.getClass()}" >>output.txt
    """
}

workflow {
    sample1 = record(id: "NotANumber",path: file("dummy.txt", checkIfExists: false))
    //sample1 = record(id: 1.1 as Float,path: file("dummy.txt", checkIfExists: false))
    //This is the only one that fails
    //sample1 = record(id: 1,path: "NotAPath")
    hello(sample1)   
}

workflow {
    sample1 = record(id: "notNumber")
    
    hello(sample1)
}

Program output

The issue is that only the case of NotAPath fails with the expected:

Caused by:
  Not a valid path value: 'NotAPath'

Environment

• Nextflow version: 6.04.0
• Java version: openjdk 17.0.18 2026-01-20
• Operating system: macOS
• Bash version: zsh 5.9 (arm64-apple-darwin25.0)

Start by running the minimal reproduction from the issue with type checking enabled, then trace how the Sample record is validated when passed to the process input. Done means values that do not match the declared Boolean, Float, and Path types are consistently rejected, while valid values continue to work.
