[Enhancement] Improve error messages for API configuration save #2973
Description
When a value fails validation, the error message is returned in the body. When multiple errors occur, they are concatenated in the body. This makes parsing very difficult in the applications using this:
Getting:
500
body: "Value '6144' for configuration property 'memory' is invalid, reason: requires memory in MiB >= 9216\n" +
"Value '19' for configuration property 'disk-size' is invalid, reason: requires disk size in GiB >= 31\n"
Is not the same as:
500
[
{
"value":"memory",
"default":"9216",
"request":"6144",
"reason":"invalid",
"requires":">= 9216"
},
{
"value":"disk-size",
"default":"31",
"request":"19",
"reason":"invalid",
"requires":">= 31"
}
]
