Bookmarklet -"TypeError: Cannot read property 'trim' of null" for Link Text and Labels tools

[redking]

Hey,

I'm having an issue with the bookmarklet when using the Link Text and Labels tools. When I click on either, I see the following error in the console

Uncaught TypeError: Cannot read property 'trim' of null

arising from this line of code

return "" === axs.properties.findTextAlternatives(a, {}).trim() ? !1 : !0;

The expression axs.properties.findTextAlternatives(a, {}) is returning null.

I see this error on a number of sites - Gmail, for example. Curiously enough, both tools work fine when I test on http://khan.github.io/tota11y/

I'm using the latest version of Chrome.

Thanks for reporting @redking. I've seen this issue myself a few times - looks like a bug upstream in Accessibility Developer Tools.

We could probably change how we consume their API, though, in the meantime.

Fix coming soon upstream. GoogleChrome/accessibility-developer-tools#188

This is fixed and landed on master. Will close this once I put up a new build!

@redking Just pushed out a new version of tota11y, powered by a newer version of Accessibility Developer Tools. This issue seems fixed, but please let me know if you see it again!
