TypeError: Cannot read properties of undefined (reading 'length')

When trying to use the extension with parser function or Special:Network, nothing is displayed. This is shown in console:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'length')

Maybe this is the redirection issue again?

• Redirects cause the visualization to break #58

I also get

Uncaught (in promise) TypeError: can't access property "length", page.displayTitle is undefined
    addPages NetworkData.js:20
    addPages NetworkData.js:19
    showPages Network.js:36
[NetworkData.js:20:10](/extensions/Network/resources/js/NetworkData.js)

|enableDisplayTitle=false
does not make a difference

[JeroenDeDauw]

Still the same issue. Still caused by Cindy's changes that made the extension blow up as soon as there is a redirect somewhere. I've not fixed this since she got paid to make those changes, so I do not feel like I should be the one cleaning up afterwards. I'm more inclined to revert.

I was under the impression that #73 fixed the issue. The last time I tried to look at this, I was stymied by #71. I will take a look again now that I am aware that there is still an issue.

This should be fixed by #92.
