Suggested Fixes
- Ensure that the value of
typein the Schema Object is not set to a value other thanarray. - Type names are compared in a case-sensitive manner.
- If you use the
minItemskeyword, ensure that the data instance you intend to validate can be an array. - If the type of the instance can vary i.e. it can be an array or some other type, consider removing the
typekeyword to allow any types. If you use theoneOf/anyOfconstructs instead, consider moving theminItemsto theoneOf/anyOfschema that has the type set asarray.
