What steps will reproduce the bug?

  1. Create a file leveraging an experimental feature (ex module mocks)
  2. Run the file via CLI with the --no-warnings flag
    1. Notice no experimental warning is printed
  3. Remove the flag from the CLI command, and add "warnings: false" to node.config.json (and include via that CLI flag)
    1. Notice an experimental warning IS printed

How often does it reproduce? Is there a required condition?

100%

What is the expected behavior? Why is that the expected behavior?

nodeOptions.warnings: false behaves the same as its CLI flag --no-warnings

What do you see instead?

Warnings

    Can you provide your config file json? There is no --warnings flag. There is --no-warnings that can be either true or false

    I think I got the issue, @marco-ippolito . This occurs when the boolean option is true by default. It is not adding the negation flag. We have to ensure it.

    I opened a PR with the fix.
