Within the same lifecycle rule or among multiple rules with the same prefix, the NoncurrentVersionTransitions field contains duplicate values for the StorageClass parameter.

Root cause

Within the same lifecycle rule or among multiple rules with the same prefix, the NoncurrentVersionTransitions field contains duplicate values for the StorageClass parameter.

Example

Scenario 1: The same rule includes transition rules to infrequent access storage at 30 days and 40 days.

{
"Rules": [{
"ID": "id",
"Prefix": "prefix",
"Status": "Enabled",
"NoncurrentVersionTransitions": [
{
"StorageClass": "IA",
"NonCurrentDays": 30
},
{
"StorageClass": "IA",
"NonCurrentDays": 40
}
]
}]
}

Scenario 2: Multiple rules with the same prefix configure transition rules to infrequent access storage at 30 days and 40 days respectively.

{
"Rules": [
{
"ID": "id",
"Prefix": "prefix",
"Status": "Enabled",
"NoncurrentVersionTransitions": [
{
"StorageClass": "IA",
"NonCurrentDays": 30
}
]
},
{
"ID": "id1",
"Prefix": "prefix",
"Status": "Enabled",
"NoncurrentVersionTransitions": [
{
"StorageClass": "IA",
"NonCurrentDays": 40
}
]
}
]
}

Solution

Ensure the StorageClass field values are unique across multiple configurations of NoncurrentVersionTransitions.
