If there is an update on SDC TOSCA node type, you need to delete Cassandra database file from SDC VM, and download docker images
On SDC VM, run: ubuntu@vm03-sdc:~$ tail -f /data/logs/BE/SDC/SDC-BE/debug.log
root@vm03-sdc:~# ls -l /data/logs/sdc-sanity/ExtentReport/SDC*.html -rw-r--r-- 1 root root 31929 Oct 29 13:51 /data/logs/sdc-sanity/ExtentReport/SDC_CI_Extent_Report.html
SDC ignores zip file in vendor CSAR Artifacts/ directory. See - SDC-483Getting issue details... STATUS
The workaround is after VSP onboarding and import, go to Deployment Artifacts on VNF design GUI, and click Add Artifact then choose Type as Other. From there you should be able to upload your zip file. The zip file will be stored under Artifacts/Other directory of SDC output TOSCA CSAR file.
