10
12 Errors thrown by Search::Elasticsearch are error objects, which can
13 include a stack trace and information to help debug problems. An error
14 object consists of the following:
15
16 {
17 type => $type, # eg Missing
18 text => 'Error message',
19 vars => {...}, # vars which may help to explain the error
20 stack => [...], # a stack trace
21 }
22
23 The $Search::Elasticsearch::Error::DEBUG variable can be set to 1 or 2
24 to increase the verbosity of errors.
25
26 Error objects stringify to a human readable error message when used in
27 text context (for example: "print 'Oh no! '.$error"). They also
28 support the "TO_JSON" method to support conversion to JSON when
29 "convert_blessed" in JSON is enabled.
30
32 The following error classes are defined:
33
34 · "Search::Elasticsearch::Error::Param"
35
36 A bad parameter has been passed to a method.
37
38 · "Search::Elasticsearch::Error::Request"
39
40 There was some generic error performing your request in
41 Elasticsearch. This error is triggered by HTTP status codes 400
42 and 500. This class has the following sub-classes:
43
44 · "Search::Elasticsearch::Error::Unauthorized"

54
55 · "Elastisearch::Error::Conflict"
56
57 Your request could not be performed because of some conflict.
58 For instance, if you try to delete a document with a particular
59 version number, and the document has already changed, it will
60 throw a "Conflict" error. If it can, it will include the
61 "current_version" in the error vars. This error is triggered by
62 the 409 HTTP status code.
63

65
66 The request body was longer than the max_content_length.
67

82
83 · "Search::Elasticsearch::Error::Unavailable"
