NAME

       JSON::Schema::Modern::Error - Contains a single error from a JSON Schema evaluation

VERSION

       version 0.569

SYNOPSIS

         use JSON::Schema::Modern;
         my $js = JSON::Schema::Modern->new;
         my $result = $js->evaluate($data, $schema);
         my @errors = $result->errors;

         my $message = $errors[0]->error;
         my $instance_location = $errors[0]->instance_location;

         my $errors_encoded = encode_json(\@errors);

DESCRIPTION

       An instance of this class holds one error from evaluating a JSON Schema with
       JSON::Schema::Modern.

ATTRIBUTES

   keyword
       The keyword that produced the error; might be "undef".

   instance_location
       The path in the instance where the error occurred; encoded as per the JSON Pointer
       specification (RFC 6901 <https://datatracker.ietf.org/doc/html/rfc6901>).

   keyword_location
       The schema path taken during evaluation to arrive at the error; encoded as per the JSON
       Pointer specification (RFC 6901 <https://datatracker.ietf.org/doc/html/rfc6901>).

   absolute_keyword_location
       The canonical URI or URI reference of the location in the schema where the error occurred;
       not defined, if there is no base URI for the schema and no $ref was followed. Note that
       this is not a fragmentless URI in most cases, as the indicated error will occur at a path
       below the position where the most recent identifier had been declared in the schema.
       Further, if the schema never declared an absolute base URI (containing a scheme), this URI
       won't be absolute either.

   error
       The actual error string.

   exception
       Indicates the error's severity is sufficient to stop evaluation.

METHODS

   TO_JSON
       Returns a data structure suitable for serialization. Corresponds to one output unit as
       specified in
       <https://json-schema.org/draft/2019-09/json-schema-core.html#rfc.section.10.4.2> and
       <https://json-schema.org/draft/2019-09/output/schema>, except that "instanceLocation" and
       "keywordLocation" are JSON pointers, not URI fragments. (See the "strict_basic"
       "output_format" in JSON::Schema::Modern if the distinction is important to you.)

   dump
       Returns a JSON string representing the error object, according to the specification
       <https://json-schema.org/draft/2019-09/json-schema-core.html#rfc.section.10>.
