AWS CodeBuild Reports status "Incomplete"

Hi,

I am testing report in AWS CodeBuild, and I can't understand why the report is always in "Incomplete" status?

Buildspec:

version: 0.2

phases:
  install:
    runtime-versions:
      docker: 20
      
  pre_build:
    commands:
      - echo "Installing Trivy..."
      - rpm -ivh https://github.com/aquasecurity/trivy/releases/download/v0.18.3/trivy_0.18.3_Linux-64bit.rpm


  build:
    commands:
      - echo "Scanning Docker image for vulnerabilities..."
      - trivy image -f json -o trivy_results.json nginx
reports:
  trivy-scan:
    files:
      - 'trivy_results.json'
    base-directory: '/'
    discard-paths: no

Report status:

I checked permissions are fine:

"Effect": "Allow",
            "Action": [
                "codebuild:CreateReportGroup",
                "codebuild:CreateReport",
                "codebuild:UpdateReport",
                "codebuild:BatchPutTestCases",
                "codebuild:BatchPutCodeCoverages"
            ],
