1)We have been facing this issue chronically for about a month. Support recommended this KB which we followed:
https://support.solarwinds.com/SuccessCenter/s/article/There-was-an-error-retrieving-data-from-SolarWinds-Information-Service-Invoke-failed
2)Basically support is telling us to upgrade to 2019.4. Just wondering if anyone else faced this issue with 12.4 and if we can expect a fix with 20194. It is a pretty generic error message.
We are hoping 2019.4 offers some relief. We have really been struggling with 12.4.
