Suggested Fixes
- Ensure that the value of
type
in the Schema Object is not set to a value other thanobject
. - Type names are compared in a case-sensitive manner.
- If you use the
patternProperties
keyword, ensure that the data instance you intend to validate can be an object. - If the type of the instance can vary i.e. it can be an object or some other type, consider removing the
type
keyword to allow any types. If you use theoneOf
/anyOf
constructs instead, consider moving thepatternProperties
to theoneOf
/anyOf
schema that has the type set asobject
.
