Can't download artifacts from S3

I have buildspec.yml
```
version: 0.2

phases:
build:
commands:
- #some commands
artifacts:
files: '**/*'
base-directory:
```

and in Jenkinsfile configuration for run CodeBuild
```
stage('Execute CodeBuild') {
steps {
withAWS(region: params.region, role: params.role, roleAccount: params.sdlcAccount) {
awsCodeBuild(
credentialsType: 'keys',
projectName: "${params.codebuildProject}",
region: "${params.region}",
sourceControlType: 'jenkins',
sourceTypeOverride: 'S3',
sourceLocationOverride: "${params.s3Bucket}/tests/${JOB_BASE_NAME}/${BUILD_ID}/source.zip",
buildSpecFile: '.jenkins/bat-api/buildspec.yml',
envVariables: "[{ENV,${params.env}},{REGION,${getRegion()}}]",
artifactTypeOverride: 'S3',
artifactPackagingOverride: 'ZIP',
artifactLocationOverride: "${params.s3Bucket}",
artifactPathOverride: "tests/${JOB_BASE_NAME}/${BUILD_ID}",
artifactNameOverride: 'results.zip',
downloadArtifacts: 'true',
downloadArtifactsRelativePath: ''
)
}
}
}
```

When I execute jenkins job I get error
```
[AWS CodeBuild Plugin] Downloading artifact from location 'arn:aws:s3:::${params.s3Bucket}/tests/${JOB_BASE_NAME}/${BUILD_ID}/results.zip' to path:/home/jenkins/workspace/${JOB_BASE_NAME}/tests/${JOB_BASE_NAME}/${BUILD_ID}/results.zip
[AWS CodeBuild Plugin] Failed to create directory /home/jenkins/workspace/${JOB_BASE_NAME}/tests/${JOB_BASE_NAME}/${BUILD_ID}
```

If I remove ```downloadArtifacts: 'true' ``` and add separate step
```
s3Download(bucket: "${params.s3Bucket}", path: "tests/${JOB_BASE_NAME}/${BUILD_ID}/results.zip", file: 'results.zip')
```
everything work fine

I also tried to execute command before
```
sh "mkdir -p tests/${JOB_BASE_NAME}/${BUILD_ID}"
```

**Expected result**
/home/jenkins/workspace/${JOB_BASE_NAME}/results.zip exists

Start with the Jenkinsfile configuration using downloadArtifacts: 'true' and the plugin's artifact-download entry point; compare its S3 path and workspace-directory handling with the separate s3Download step shown. Reproduce the failure with the provided buildspec.yml and overrides, then verify that the artifact is downloaded to the expected workspace path without requiring literal Jenkins variables in directory creation.
