Error generating canonicalized entry when uploading pre-formatted entry via --entry flag

[tiziano88]

To reproduce:

in r.json (I dumped this from an existing entry, so it should definitely pass validation):

{
    "apiVersion": "0.0.1",
    "spec": {
        "data": {
            "hash": {
                "algorithm": "sha256",
                "value": "07f40565aeaed9a36a8a63e12d2aacb5d9a42319d74ae4c1afac8a178d55822b"
            }
        },
        "signature": {
            "content": "4m1UFWVSQw+kCR8cxRw7XCUY+ecLc1v3+XWc1Aru5BnS2iS1dTL4DLTaLREU0QzGN1suEtfyEzX3OnW8uneWBg==",
            "format": "x509",
            "publicKey": {
                "content": "LS0tLS1CRUdJTiBQVUJMSUMgS0VZLS0tLS0KTUNvd0JRWURLMlZ3QXlFQTN4WGRUQzdDVk1abnpzMElWWmVHYkhnMkNwdEdUNm0zOEpiR3Q0d2YrYUk9Ci0tLS0tRU5EIFBVQkxJQyBLRVktLS0tLQo="
            }
        }
    },
    "kind": "rekord"
}

then

rekor upload --entry=r.json

It worked with the following entry, specifying the inlined data (thanks @bobcallaway for the help):

{
    "apiVersion": "0.0.1",
    "spec": {
        "data": {
            "content": "j8zIk8Quak2BBi4volNIIZ+uJUQSRY2Myaq9WP9ws84="
        },
