    Description

      enum:

      The value of this keyword MUST be an array. This array SHOULD have at least one element. Elements in the array SHOULD be unique.

      https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.6.1.2

      So it is expected that JSON_SCHEMA_VALID for this schema returns warning:

      SET @schema = '{
      		 
                       "type":"array",
      		 
                        "enum": []
      		 
                      }';

      But actual result is:

      SELECT JSON_SCHEMA_VALID(@schema, '2');
      		 
      JSON_SCHEMA_VALID(@schema, '2')
      		 
      0
      		 
      SELECT JSON_SCHEMA_VALID(@schema, '[]');
      		 
      JSON_SCHEMA_VALID(@schema, '[]')
      		 
      0
      		 
      SELECT JSON_SCHEMA_VALID(@schema, null);
      		 
      JSON_SCHEMA_VALID(@schema, null)
