10 months ago In general, there is no such thing as precedence for JSON schema keywords. Keyword validation works independently (except for some newer things like unevaluatedProperties).
The order in which keywords are checked is not a bug, but an implementation detail that is not governed by spec.
A limitation of this library is that it stops processing on the first failure (to fail fast), otherwise you'd see both Required property missing: brand and Required property missing: parentage_level in the list of errors.
The schema that you shared does not make much sense to me, since root "required" invalidates some of the logical conditions in "allOf" (e.g. {"brand":"foo"} would not be valid).
"required": [
"parentage_level"
],
"allOf": [
{
"allOf": [
{
"if": {
"required": [
"parentage_level"
]
},
"then": {
"required": [
"model_name"
]
},
"else": {
"required": [
"brand"
]
}
}
]
}

allOf takes precedence over required ？
