Hi,

Is there more to this error?

FYI, there are two steps to analysis. The first step scans your project and produces an analysis report. The second step processes that report server-side. Both steps must succeed for your project to be “analyzed”, but in your case the second is failing, which is why you have an apparently successful analysis and the message that the project has not yet been analyzed.

So what is the solution for it please

Hi,
you need to modify you quality gate by putting 10 instead of 10.0% in your depulicated Lines condition
I hope it will fix your problem.
