What does this error message mean? AttributeError: "InstallerConverter" object has no attribute 'hasBCF'"Should I ignore it? Also, I have a package that becomes a grey-colored package after I apply a BCF. From what I understand, I should not be making any changes inside the archived package because that will just cause a 'mismatch' between the archived package and the BCF file. So how can I fix the grey-colored package with a BCF file that needs to be applied?
