{code}
Bucket that is causing exception has following configuration (i removed ids
from json):
{code:java}
{
"kind": "storage#bucket",
"selfLink": "",
"id": "",
"name": "",
"projectNumber": "",
"metageneration": "1",
"location": "US-CENTRAL1",
"storageClass": "STANDARD",
"etag": "CAE=",
"timeCreated": "2020-10-26T13:54:23.835Z",
"updated": "2020-10-26T13:54:23.835Z",
"cors": [
{
"origin": [
"https://*.cloud.google.com";,
"https://*.corp.google.com";,
"https://*.corp.google.com:*";
],
"method": [
"GET"
]
}
],
"iamConfiguration": {
"bucketPolicyOnly": {
"enabled": true,
"lockedTime": "2021-01-24T13:54:23.835Z"
},
"uniformBucketLevelAccess": {
"enabled": true,
"lockedTime": "2021-01-24T13:54:23.835Z"
},
"publicAccessPrevention": "unspecified"
},
"locationType": "region"
} {code}
As you can see the CORS object have no maxAgeSeconds field. This is consistent
with documentation
(https://cloud.google.com/storage/docs/cross-origin#cors-elements) where
maxAgeSeconds is described as optional.
