Do Azure Logic Apps support oneOf, anyOf in JSON schema validation - azure

Question

I was trying to add JSON schema validation with in a Logic App using ParseJSON action.
I want to validate the existence of either of the object in the message (equivalent to XSD choice).
For instance, messages may have either of lastname or familyname.
{
"name": "Alan",
"familyname": "Turing"
}
Or
{
"name": "Alan",
"lastname": "Turing"
}
I modified the generated schema as,
{
"type": "object",
"properties": {
"name": {
"type": "string"
},
"oneOf": [
{
"lastname": {
"type": "string"
}
},
{
"familyname": {
"type": "string"
}
}
]
}
}
Logic App execution throws below error
Just to test if any other schema combination keywords works, tried to test with anyOf in place of oneOf and it fails in execution as well.
Does Logic Apps support these extended validation ? Am I missing some specific syntax here ?

Answer 1

If you are validating that either familyname or lastname be present then you are missing the "required" attribute.
{
"type": "object",
"properties": {
"name": {
"type": "string"
}
},
"oneOf": [
{
"familyname": {
"type": "string"
},
"required": [ "familyname" ]
},
{
"lastname": {
"type": "string"
},
"required": [ "lastname" ]
}
]
}
This will validate the JSON. If you want to get the values out in a later step you could use the coalesce function.
#coalesce(actionBody('Parse_JSON')?['familyname'], actionBody('Parse_JSON')?['lastname'])
