The DefaultValue of a CustomProperty is incorrect type #3692
Description
Since GitHub added support for multi-select it's been possible for the DefaultValue of a CustomProperty to be either a string or an array of strings; see schema below.
"default_value": {
"oneOf": [
{
"type": "string"
},
{
"type": "array",
"items": {
"type": "string"
}
}
],
"description": "Default value of the property",
"type": [
"null",
"string",
"array"
]
},Based on the existing implementation of CustomPropertyValue where Value has the same type we should modify DefaultValue to any.
