Builds failing with 'CXX-public_undocumented_api' does not exist error

[renukaholimath]

hi Team,

We have hosted SonarQube Datacenter edition v10.1.0 in our environment. Based on the request of one user, we have installed the "sonar-cxx-plugin-2.1.1.488.jar" plugin on our Pilot instance. After the plugin installation, all the builds are failing with the below error. PFA the complete scanner context error.

Is this a known issue? Could you please let us know if there is any fix available for this issue?
