Search::Elasticsearch::Error(3p)

NAME
Search::Elasticsearch::Error - Errors thrown by Search::Elasticsearch

VERSION
version 6.00

DESCRIPTION
Errors thrown by Search::Elasticsearch are error objects, which can include a stack trace and information to help debug problems. An error object consists of the following:

    {
        type  => $type,              # eg Missing
        text  => 'Error message',
        vars  => {...},              # vars which may help to explain the error
        stack => [...],              # a stack trace
    }

The $Search::Elasticsearch::Error::DEBUG variable can be set to 1 or 2 to increase the verbosity of errors.

Error objects stringify to a human readable error message when used in text context (for example: "print 'Oh no! '.$error"). They also support the "TO_JSON" method to support conversion to JSON when "convert_blessed" in JSON is enabled.

ERROR CLASSES
The following error classes are defined:

•   "Search::Elasticsearch::Error::Param"

    A bad parameter has been passed to a method.

•   "Search::Elasticsearch::Error::Request"

    There was some generic error performing your request in Elasticsearch. This error is triggered by HTTP status codes 400 and 500. This class has the following sub-classes:

    •   "Search::Elasticsearch::Error::Unauthorized"

        Invalid (or no) username/password provided as "userinfo" for a password protected service. These errors are triggered by the 401 HTTP status code.

    •   "Search::Elasticsearch::Error::Missing"

        A resource that you requested was not found. These errors are triggered by the 404 HTTP status code.

    •   "Elastisearch::Error::Conflict"

        Your request could not be performed because of some conflict. For instance, if you try to delete a document with a particular version number, and the document has already changed, it will throw a "Conflict" error. If it can, it will include the "current_version" in the error vars. This error is triggered by the 409 HTTP status code.

    •   "Search::Elasticsearch::Error::ContentLength"

        The request body was longer than the max_content_length.

    •   "Search::Elasticsearch::Error::RequestTimeout"

        The request took longer than the specified "timeout". Currently only applies to the cluster_health request.

•   "Search::Elasticsearch::Error::Timeout"

    The request timed out.

•   "Search::Elasticsearch::Error::Cxn"

    There was an error connecting to a node in the cluster. This error indicates node failure and will be retried on another node. This error has the following sub-classes:

    •   "Search::Elasticsearch::Error::Unavailable"

        The current node is unable to handle your request at the moment. Your request will be retried on another node. This error is triggered by the 503 HTTP status code.

    •   "Search::Elasticsearch::Error::BadGateway"

        A proxy between the client and Elasticsearch is unable to connect to Elasticsearch. This error is triggered by the 502 HTTP status code.

    •   "Search::Elasticsearch::Error::GatewayTimeout"

        A proxy between the client and Elasticsearch is unable to connect to Elasticsearch within its own timeout. This error is triggered by the 504 HTTP status code.

    •   "Search::Elasticsearch::Error::SSL"

        There was a problem validating the SSL certificate. Not all backends support this error type.

•   "Search::Elasticsearch::Error::Forbidden"

    Either the cluster was unable to process the request because it is currently blocking, eg there are not enough master nodes to form a cluster, or because the authenticated user is trying to perform an unauthorized action. This error is triggered by the 403 HTTP status code.

•   "Search::Elasticsearch::Error::Illegal"

    You have attempted to perform an illegal operation. For instance, you attempted to use a Scroll helper in a different process after forking.

•   "Search::Elasticsearch::Error::Serializer"

    There was an error serializing a variable or deserializing a string.

•   "Elasticsarch::Error::Internal"

    An internal error occurred - please report this as a bug in this module.
