Loading the zookeeper browser page is failing with error

[chrajeshbabu]

zookeeper browser always giving blank page. When I dig deeper found the following error.

main.js:17441 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'numChildren') at main.js:17441:59 at Array.map (<anonymous>) at main.js:17435:19

it's happening while forming the tree structure with zookeeper data.

Here getting null, need to check how currentNodeListStat[pathName] could be null. https://github.com/apache/pinot/blob/b067ae1924a532282229e0506188b9375f0ec6d2/pinot-controller/src/main/resources/app/utils/PinotMethodUtils.ts#L704
