Hello,

I am getting the following error. I have not changed anything about how I call the scanner. The scan is done in a Github workflow, which has not changed either.

	at org.sonar.core.platform.ComponentContainer$ExtendedDefaultPicoContainer.getComponent(ComponentContainer.java:50)
	... 23 common frames omitted

Hi,

What’s the name of the branch in question, and probably more importantly, what’s your long-lived branch pattern? You’ll find it at the top-right of the Branches page.
