Description search.protobuf file download failed

When I try to upgrade sonarqube directly from 7.9.2 to 8.9.3, when I call /api/qualityprofiles/search.protobuf?project=XXXX, it prompts An error has occurred. Please contact your admininistrator, and the log prompts NullPointerException. The original sonarqube can be accessed normally, but the new sonarqube is not. This is related to my use of mvn sonar:sonar to scan. I tried to look through the source code, but I didn’t find any useful information, nor did I find any useful information on the Internet.
