Expected behavior

Clicking on a button to direct to another page, should not dispaly an error in the Console.

Actual behavior

Clicking on a button to direct to another page using the dmx-on:click="browser1.goto('/dashboard' ,true)

Gives this error in the browser console. Although I get directed to the correct page.

How to reproduce

Create a button on dynamic event on click - browser - provide a url to another page.

Save the page.
Click on the button and see the error on the browser console.

Please note, I noticed this error following the extensions update released yesterday.

Do you have a link (<a> tag) on the page without a href?

Hi @patrick

No I don't.

I have a dynamic event on a button that when on click should take to another page and it does as well. However I get above error on the browser console.

Here is the code snippet:

 <button id="btn2" class="btn" dmx-on:click="browser1.goto('/scope/manage_scope/',true)"><i class="fa-regular fa-folder-open"></i>&nbsp;Quals Management</button>

I think that I found the place of the error but that should only happen on a link without a href. You're sure that you don't have some anchor node on the page?

Here an update for the issue:
dmxRouting.zip (10.0 KB)

Thanks @patrick

It solved the issue. I don't get the error on the browser console after using the dmxRouting files you shared above. It will be great to have these included in the next release/update.

Cheers
