The command to upload is:

curl -sS -X POST "$DD_ENDPOINT/api/v2/import-scan/" \
  -H "Authorization: Token $DD_TOKEN" \
  -F "scan_type=Nuclei Scan" \
  -F "engagement=$ENGAGEMENT_ID" \
  -F "active=true" \
  -F "verified=false" \
  -F "minimum_severity=Info" \
  -F "file=@nuclei.jsonl";

The scan is for a dvwa container deploy. Attach the report.

Renamed to txt (github can not upload jsonl files)
nuclei.txt
