ANDI not functioning on ServiceNow "Tokyo" release #184

Closed stevekram closed 1 year ago

stevekram commented 1 year ago

Hello, Our organization recently updated one of their ServiceNow environments from "Rome" to "Tokyo" (see https://www.servicenow.com/community/now-platform-articles/servicenow-versions/ta-p/2312014). ANDI works successfully on the older "Rome" in both Chrome and Firefox, but results in a blank locked-up session using "Tokyo". This is repeatable in current versions of Chrome, FireFox, and Edge. We see no indications why activating ANDI results in the ServiceNow screen becoming unresponsive. Screen capture shows ANDI functionality on "Rome" ServiceNow page, and the same page when activating ANDI using ServiceNow "Tokyo".

Thanks.

Hi Steve. Please see if answers/workarounds on the FAQ page addresses this issue for you:

John,

Since we can successfully run ANDI on the “R”ome version of ServiceNow (verified in various browsers) but not “T”okyo, we feel we’ve eliminated CSP and Huge Test Page as potential causes. The JavaScript “favelet test” runs successfully, but we did note one new “Uncaught SyntaxError” when we launch ANDI.

@.*** We’ve verified this does NOT appear in the previous ServiceNow environment.

Hopefully this helps.

Can you please provide the error info (line number) for the syntax issue?

That isn't a reference to anything that ANDI is using. I would assume that error might be present before ANDI is launched.

If you've already ruled out presence of iframes by following the FAQ, then the other thing that may cause the issue is if the page is rendered using shadow DOM. At this time, ANDI cannot detect shadow DOM content.

stevekram commented 1 year ago

John,

I carefully re-executed the iframes work-around actions, and am now able to operate ANDI on the “T”okyo version of ServiceNow. 😊

Do we forever need to apply this work-around, or is there a update planned for ANDI that will handle ServiceNow’s iframes implementation?

Thanks.

Steve K.

Unfortunately, there isn't a way with ANDI to make this more streamlined. It's a limitation of what abilities browsers allow for externally executed scripts.

stevekram commented 1 year ago

We understand. Thanks for checking, John.
