Describe the bug
When having a group hierarchy, clicking on a child group in the left panel of the admin groups management UI throws an exception in the web browser console.
Version
26.7.3
Regression
- The issue is a regression
Expected behavior
The UI should display on the right panel the content of the group.
Actual behavior
When using Firefox 140.14.0esr (64-bit), we get the following error:
Danger alert:can't access property "map", ge is null
With Chromium 151.0.7922.173 (Official Build), we get the following error:
Cannot read properties of null (reading 'map')
The Chromium console sources points to the following line:
return ge.map( (pe, I) => {
const V = l ? l(pe) : !1
, q = [{
data: pe,
disableSelection: V,
disableActions: V,
selected: !!_.find(K => cn(K, "id") === cn(pe, "id")),
isOpen: se(pe) ? !1 : void 0,
cells: Le(u, pe)
}];
return s && q.push({
parent: I * 2,
cells: se(pe) ? Le(s, pe) : []
}),
q
}How to Reproduce?
Reproduced with the official 26.7.3 docker image.

- create a parent group
Parent Group - create a child group

- on the left panel with the hierarchy, click on

We face the same issue. The URL is not build correctly. Instead of a slash between parent-group and child-group an %2F is set. If you replace it manually by / and do a refresh group will show up.

Hello,
i'm facing the same issue. downgrading to 26.7.2 solves it.
Same Issue with the encoding (/ %2F) as described by @npourie
