For more context: these popped up a few days ago and I didn’t understand why. But now I got the bottom of it: I was using the Sonar Way (recommended) profile, but a few days ago that was removed: JavaScript and TypeScript "Sonar Way (recommended)" profile upgraded.
So as part of the new profile I got the S1172 rule which apparently gives a false positive on ‘parameter properties’ (https://www.typescriptlang.org/docs/handbook/2/classes.html#parameter-properties) in typescript. The constructor in this case will usually have an empty body.
I also don’t want to disable the rule completely, what’s next?
