error: null is not an object (evaluating 'this.view2.body')

[chrwei]

recently upgraded to react 18.1.0 and rc-easyui 1.2.6 and got this error in my log. I have an ErrorBoundary setup that captures errors and send them to my sever.

I have not been able to reproduce it, but I think the user has a mac and I don't have access to one at the moment. user agent is: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.4 Safari/605.1.15

maybe relayed, I'm also getting "Cannot read properties of null (reading 'body')" that I can reproduce, but as far as I can tell that one isn't coming from jeasyui.  "this.view2.body" is pretty clearly from your datagrid.  I'm seeing it on only 2 of my pages, and both use groupField/renderGroup.  I have not seen it on pages that have datagrids that aren't grouped.

more errors logged as i posted this

one from another mac user, same user agent

several other users, slightly different error, all firefox

"error: this.view2 is null "
user agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0

oddly, if I tell the ErrorBoundery to not treat these as error, everything renders fine anyway.

I'm using @apollo/client 3.6.5 to provide the grid "data".  I was using 3.3.14 before. maybe related. looking at the network tab in devtools everything seems to be as I'd expect, no null results

Cannot read property 'body' of null


I'm pretty sure these are all the same error, I do see some null check on view2, but not everywhere.  I still can't figure why it's null, or at what point.  I'm also not sure how view2 relates to my data or code.

think i found the issue.  In the GridColumn's render I'm using a lazy load, that component has to separately be wrapped in a Suspense to avoid the error.  I do have my <App /> wrapped in a Suspense, but it seems GridColumn is breaking out of that somehow
