Hello @guwirth,
This is a bug, fixed in SonarQube 8.1. See https://jira.sonarsource.com/browse/SONAR-12728.
As an interim (until you upgrade or 8.1 or higher), you should query all measures except for the metric new_development_cost
Regards
Hello Günther,
As per the ticket I pointed and given its severity there is no plan to backport on 7.9. The workaround I provided (once you get all the metrics from the API, just remove new_development_cost from the list before invoke api/measures/component and it’ll work) seems acceptable, an not having access to this measure does not seem critical.
Regards
