Hi, I was trying to create "cryptoRefArray" like the protocol example of CBOM.
However, My code generates slightly different results from the protocol example and the results is not valid by schema validation.
So, I'd like to ask you how to change my code for valid CryptoRefArray.
Thank you.

1. Protocol Example
   https://github.com/CycloneDX/bom-examples/blob/master/CBOM/Protocol/bom.json

"cryptoRefArray": [
"crypto/certificate/google.com@sha256:1e15e0fbd3ce95bde5945633ae96add551341b11e5bae7bba12e98ad84a5beb4"
]

2. My code

// CryptoRef instance
List ref = new ArrayList<>();
ref.add("crypto/certificate/google.com@sha256:1e15e0fbd3ce95bde5945633ae96add551341b11e5bae7bba12e98ad84a5beb4");

CryptoRef cryptoRef = new CryptoRef();    
cryptoRef.setRef(ref);

// setCryptoRefArray ( parameter is cryptoRef instead of List )
protocolComponent.getCryptoProperties().getProtocolProperties().setCryptoRefArray(cryptoRef);

3. The results of my code

  "cryptoRefArray" : {
	"ref" : [  "crypto/certificate/google.com@sha256:1e15e0fbd3ce95bde5945633ae96add551341b11e5bae7bba12e98ad84a5beb4"
	]
  }
