GuardianErrorExitCodeException: checkov completed with an Error exit code: 1. An error has occurred running the Checkov tool.

使用提供的 Checkov 命令输出作为起点，在有配置文件和没有配置文件的情况下分别复现 MicrosoftSecurityDevOps@1 任务。检查生成的 checkov.sarif 和 msdo.sarif 文件，并比较该任务对 DownloadExternalModules 参数的处理方式。当配置的扫描产生可用的 SARIF 结果，且外部模块的行为与所提供的设置一致时，即视为完成。

Hello All!

When i use almost vanilla MicrosoftSecurityDevOps@1 template:

parameters:
  TemplatesRepoName: ''

stages:
- stage: Microsoft_Defender
  displayName: Microsoft Defender for Cloud DevOps security
  condition: always()
  pool:
    vmImage: windows-latest
  jobs:

    displayName: Scan
    steps:
    - checkout: ${{ parameters.TemplatesRepoName }}
    - checkout: self
          
    - task: MicrosoftSecurityDevOps@1
      displayName: Microsoft Security DevOps
      inputs:
        config: templates/configs/checkov.gdnconfig
        categories: IaC

Inside pipeline:

resources:
  repositories:
    - repository: templates
      type: git
      name: PROJ/templates
      ref: refs/heads/feature/microsoft-defender-config

trigger:

in the end, i got an error:

My config file is really basic:

{
    "tools": [
      {
        "tool": {
          "name": "Checkov",
          "version": "Latest"
        },
        "arguments": {
          "DownloadExternalModules": "false",
          "TargetDirectory": "$(Checkov.DefaultTargetDirectory)"
        }
      }
    ]
  }

Even when i set DownloadExternalModules to false, i got an error in cmd:

/home/vsts/work/_msdo/packages/nuget/Microsoft.Guardian.CheckovRedist_linux_amd64.3.2.144/tools/dist/checkov --download-external-modules false --directory ./ --output-file-path /home/vsts/work/1/s/.gdn/.r/checkov/001/checkov.sarif
##[error]2024-07-08 13:06:05,846 [MainThread  ] [WARNI]  Failed to download module git::https://[email protected]/ORD/PROK/_git/keyvault//src?ref=v0.3:None (for external modules, the --download-external-modules flag is required)

That error is hilarious since flag is set to false but leave that...

The problem that i have is that i have a lot of errors from that pipeline:

For better reference, output with env variable set to DEBUG:
https://gist.github.com/michasacuer/c0e7127bfe537f1a15e19db5fcd8fa81

And also, sarif file is empty. This is an output from my code:

{
  "$schema": "https://schemastore.azurewebsites.net/schemas/json/sarif-2.1.0-rtm.5.json",
  "version": "2.1.0",
  "runs": [],
  "properties": {
    "producer": "MicrosoftSecurityDevOps"
  }
}

And scans tab in devops is empty.

When i don't use config file i got an output from msdo.safir file and scans tab has entries:

But task looks like this:

    - task: MicrosoftSecurityDevOps@1
      displayName: Microsoft Security DevOps
      inputs:
        categories: IaC

And still i got this error:

And output:

/home/vsts/work/_msdo/packages/nuget/Microsoft.Guardian.CheckovRedist_linux_amd64.3.2.144/tools/dist/checkov --directory ./ --output sarif --soft-fail --output-file-path /home/vsts/work/1/s/.gdn/.r/checkov/001/checkov.sarif
##[error]2024-07-08 13:00:23,785 [MainThread  ] [WARNI]  Failed to download module git::https://[email protected]/BarentzDevOps/PROJ/_git/keyvault//src?ref=v0.3:None (for external modules, the --download-external-modules flag is required)

So, to sum up:

1. When i provide config scans outputs are not saved to file
2. Even with variable set to false checkov yells that download modules var is required

Why it fails? What i do wrong?
