Hi @JoseEspinosa,

It looks like this pull-request is has been made against the JoseEspinosa/nf-core-tools master branch.
The master branch on nf-core repositories should always contain code from the latest release.
Because of this, PRs to master are only allowed if they come from the JoseEspinosa/nf-core-tools dev branch.

You do not need to close this PR, you can change the target branch to dev by clicking the "Edit" button at the top of this page.
Note that even after this, the test will continue to show as failing until you push a new commit.

Thanks again for your contribution!

I think we should disable the truthy checks, because it generates too many false-positives. Alternatively, add on: # yamllint disable-line rule:truthy etc. to these lines.
