Hi,

Welcome to the community!

This error is coming from a 3rd-party plugin, possibly this one(?). You should file an issue with your plugin provider and give them this full stacktrace and if possible code to reproduce the error.

HTH,
Ann

Thank you very much Ann. Kind regards

Hi Ann,
how do you know that it comes from the 3rd party plugin? What is the indication for it?

ganncamp · March 16, 2022, 11:55am

Hi,

The stacktrace itself is the indication:

HTH,
Ann

Hello, thanks for the issue report. We’ve had a look at this UnableToSupportSlingSchedulerCheck NPE · Issue #217 · wttech/AEM-Rules-for-SonarQube · GitHub and it appears to come from another plugin. com.adobe.platform.experience isn’t a package we’ve developed.

My guess is that the rule comes from a custom set that Adobe have integrated into their Sonar checks as part of the Cloud Manager pipelines. I don’t think that code is open source. At least I’ve been unable to find it via a quick Google search.
