my DynamoDB partition key is h(string) and sort key r(string)
loki error log:
level=warn ts=2022-10-17T09:22:34.686730018Z caller=dynamodb_storage_client.go:220 msg=“Data lost while flushing to DynamoDB” err=“ValidationException: The provided key element does not match the schema\n\tstatus code: 400, request id: IR1O2JMNHBQVV7PPONCC8PMHTRVV4KQNSO5AEMVJXXXXXX”
