I find myself running into this issue on a fairly frequent basis, and other users have been reporting it more and more.
When viewing the data tab for a survey, when you click a record it pops up this panel on the right hand side to display the record, however I am finding frequently this panel will not load, I have seen no loading at all or loading some questions but spinning endlessly and never finishing loading. It happens on some surveys but not all and not every time on the same survey, even ones that are essentially copies of each other, the more records the more likely this happens it seems.
Are there issues with the way I have my surveys set up that cause this, or is it just a general lack of reliability from this web page?
Are these surveys published with Survey123 Connect?
The panel uses the web form, so it might not support the functionality you have used in the survey design?
Yes they are published with Connect.
I was wondering if it was something like this, however it does load properly sometimes, but not others, so it can read them.
I've found more recently that I have to toggle the switch a few times to get it to show. Kind of the reverse of its old behaviour where I had to toggle the switch a few times to hide it.
I have reached out to Esri Support (Canada) and sent them a HAR file, the XLSX for them to try as well, and did a call with them yesterday to show the error. The HAR apparently did not show anything while looking at the network data in the dev tools in Edge, but when we looked at the Console section it shows a couple errors.
This is just me speculating, but something about the "ForEach" being in the error makes me want to connect it to the repeats in my surveys, but of course I have no idea.
The error above is what I got looking this morning, yesterday one of the errors expanded and was very very long, but these ones are not.
