We have two Apex environments that are supposed to be the same; at least I can verify that they are all 24.1.2.
The problem I am experiencing is the application works fine in one environment but produces an UI error in the other one. The symptom is on some pages, when I click on an editable cell of some interactive grid, I get error popups that says Unexpected end of JSON input, and after a few clicks to close those popups, the browser console shows the error below:
Blocked aria-hidden on a <input> element because the element that just received focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.
It only happens on some pages. So, the first thought would be comparing those pages, but on a second thought, all pages work fine in one environment, so perhaps the problem is not on the pages themselves ?
I tried switching themes but it didn't help.
Sorry for the vague details. Any ideas what else I should check?
Thanks,
