-----------------------------------
Summary: Error accessing property 'INDEX.sizeInBytes' in Solr Cloud
Key: SOLR-17312
URL: https://issues.apache.org/jira/browse/SOLR-17312
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Admin UI
Affects Versions: 8.11.1
Environment: Solr cloud on EC2 AWS, with zookeeper on EC2 AWS.
Reporter: Antony VEYRE
We have encountered a recurring issue in our Solr Cloud environment where
attempts to access the 'INDEX.sizeInBytes' property result in a TypeError. This
seems to occur sporadically when loading our dashboard that visualizes Solr
metrics.
Steps to Reproduce:
# Launch the Solr Cloud dashboard when one or more collections has replicas
"down"
# Observe the error in the JavaScript console as soon as the dashboard tries
to fetch index statistics.
Actual Results: The JavaScript console throws the following error:

Possibly unhandled rejection: {} {color}
Expected Results: The dashboard should load without errors, and index
statistics should be displayed correctly.
Additional Information:
* The issue appears to be linked with how data is fetched or processed before
being passed to the AngularJS frontend.
* Any insights or suggestions on how to prevent this type of error would be
greatly appreciated.
