Unsafe attempt to initiate navigation for frame with origin 'https://docs.google.com' from frame with URL 'https://localhost:3000/taxonomytool-impl.html'. The frame attempting navigation of the top-level window is sandboxed, but the flag of 'allow-top-navigation' or 'allow-top-navigation-by-user-activation' is not set.

Ahhh yeah I think I'm finding that too. Honestly though new tab is not a bad alternative. Thanks for your help here @enuchi and appreciate all the work you've put into this library!

@WillLiuMH sounds like it's happening when you are working in local development. Does it happen when you deploy the app (npm run deploy)?

[WillLiuMH]

Hey @enuchi, yeah I'm getting the same issue in both the development and deployed versions. I just need get that attribute set on the iframe somehow and I think it should be good, but just scratching my head at how to do that...

Also just wanted to say thanks for writing this library. It's been kick ass so far!

[enuchi]

Glad it's been helpful to you!

If I understand what's happening correctly then you are not going to be able to modify the top level iframe because Google does not expose that capability. I don't believe you're able to navigate to another page within the iframe -- can you take a look here? https://developers.google.com/apps-script/guides/html/restrictions#restrictions_in_iframe_mode

What happens if you add a link with the target="_top" attribute?

<a href="http://google.com" target="_top">Click Me!</a>

[WillLiuMH]

Hmmm I tried that, no change. Looking at the article you linked, the _top attribute is actually supposed to go into the tag in the html sheet, which you already had there. I feel like there's got to be a way to add a link to a google sheets web app!!!

[enuchi]

I don't think it's going to work. I'm guessing Google really doesn't want you to navigate to another page within its UI, for security reasons. Your best bet is to launch your page in a new tab with target _blank: <a href="http://www.yourpage.com" target="_blank">
