Vue getComponentName returns function instead of 'undefined'

Question

I have a project I've been working on upgrading from Vue 2.6 to 2.7, and have ironed out most of the kinks. However, there are a couple files that are written with cased props, which vue tries to generate a Vue Tip for, which looks like this: Vue Tip Image

While generating this tip, there is a section of code that should evaluate to 'undefined' in a method called getComponentName(), as shown below with chrome's devtools: Successful run

That is what is supposed to happen, however when I am running the project I am updating, that method instead evaluates to a function, which causes an error later on and eventually breaks the entire app. Unsuccessful run

Here is the contents of the function, it is pretty straightforward:

function getComponentName(options) {
    return options.name || options.__name || options._componentTag;
}

My guess is somewhere my versioning is off, so here is my package.json file. Any help is greatly appreciated!

Answer 1

This doesn't answer the f() vs undefined question, but how about adding || false to have either key (name, __name, _componentTag) or false?

function getComponentName(options) {
    return options.name || options.__name || options._componentTag || false;
}
