moduleBinaries param cannot be set in main.nf file

[davidmasp]

Bug report

Coming from this question (https://github.com/nextflow-io/nextflow/discussions/5203)

Expected behavior and actual behavior

According to the documentation, see here, when using module binaries we should include the parameter nextflow.enable.moduleBinaries either in the main file or in the configuration file.

To enable this feature, enable the following flag in your pipeline script or configuration file:

Including the parameter in the config file works as expected, however, including it in the main.nf file results in the following error.

$ nextflow run main.nf
Nextflow 24.04.4 is available - Please consider updating your version to it

 N E X T F L O W   ~  version 24.04.3

Launching `main.nf` [kickass_agnesi] DSL2 - revision: 8091327fbc

ERROR ~ No such variable: moduleBinaries

 -- Check script 'main.nf' at line: 3 or see '.nextflow.log' file for more details

Steps to reproduce the problem

I have created a fork of the nextflow-io/hello repository to test this, see below:

https://github.com/davidmasp/hello-modbins

See commit -> 3766dd9 for the expected behavior when parameter is set in the config file. See last commit -> 5c91c64 for breaking behavior when parameter is set in the main.nf file

Program output
