SonarLint error: 'markers' has encountered a problem

Hi, when we Analyze our cobol programs using SonarLint we encounter the error:
’markers’ has encountered a problem.
An internal error has occurred.
java.lang.NullPointerException

Even though we encounter the above error, we can still see the issues of the cobol program in the SonarLint Report tab.

How can we remove the error? Thank you!
