16 result => $hashref,

20 This class defines a hierarchy of exception objects.
21
23 Unless otherwise explicitly documented, all driver methods throw
24 exceptions if an error occurs.
25 To catch and handle errors, the Try::Tiny and Safe::Isa modules are
27 recommended:
28 use Try::Tiny;
30 use Safe::Isa; # provides $_isa
31 try {
33 $coll->insert( $doc )
34 }
35 catch {
36 if ( $_->$_isa("MongoDB::DuplicateKeyError" ) ) {
37 ...
38 }
39 else {
40 ...
41 }
42 };
43 To retry failures automatically, consider using Try::Tiny::Retry.

92 All classes inherit from "MongoDB::Error".
94 All error classes have the attribute:
96 · message — a text representation of the error
98 MongoDB::AuthError
100 This error indicates a problem with authentication, either in the
101 underlying mechanism or a problem authenticating with the server.
102 MongoDB::ConnectionError
104 Errors related to network connections.
105 MongoDB::HandshakeError
107 This error is thrown when a connection has been made, but SSL or
109 authentication handshakes fail.
110 MongoDB::NetworkError
112 This error is thrown when a socket error occurs, when the wrong number
114 of bytes are read, or other wire-related errors occur.
115 MongoDB::ConfigurationError
117 This error is thrown when there is a configuration error between the
118 MongoDB deployment and the configuration of the client, such as when
119 trying to use explicit sessions on a MongoDB < 3.6
120 MongoDB::CursorNotFoundError
122 This error indicates that a cursor timed out on a server.
123 MongoDB::DatabaseError
125 Errors related to database operations. Specifically, when an error of
126 this type occurs, the driver has received an error condition from the
127 server.
128 Attributes include:
130 · result — response from a database command; this must implement the
132 "last_errmsg" method
133 · code — numeric error code; see "ERROR CODES"; if no code was
135 provided by the database, the "UNKNOWN_ERROR" code will be
136 substituted instead
137 MongoDB::DuplicateKeyError
139 This error indicates that a write attempted to create a document with a
141 duplicate key in a collection with a unique index. The "result"
142 attribute is a result object.
143 MongoDB::NotMasterError
145 This error indicates that a write or other state-modifying operation
147 was attempted on a server that was not a primary. The "result"
148 attribute is a MongoDB::CommandResult object.
149 MongoDB::WriteError
151 Errors indicating failure of a write command. The "result" attribute
153 is a result object.
154 MongoDB::WriteConcernError
156 Errors indicating failure of a write concern. The "result" attribute
158 is a result object.
159 MongoDB::DecodingError
161 This error indicates a problem during BSON decoding; it wraps the error
162 provided by the underlying BSON encoder. Note: Encoding errors will be
163 thrown as a "MongoDB::DocumentError".
164 MongoDB::DocumentError
166 This error indicates a problem with a document to be inserted or
167 replaced into the database, or used as an update document.
168 Attributes include:
170 · document — the document that caused the error
172 MongoDB::GridFSError
174 Errors related to GridFS operations, such a corrupted file.
175 MongoDB::InternalError
177 Errors that indicate problems in the driver itself, typically when
178 something unexpected is detected. These should be reported as
179 potential bugs.
180 MongoDB::ProtocolError
182 Errors related to the MongoDB wire protocol, typically problems parsing
183 a database response packet.
184 MongoDB::SelectionError
186 When server selection fails for a given operation, this is thrown. For
187 example, attempting a write when no primary is available or reading
188 with a specific mode and tag set and no servers match.
189 MongoDB::TimeoutError
191 These errors indicate a user-specified timeout has been exceeded.
192 MongoDB::ExecutionTimeout
194 This error is thrown when a query or command fails because
196 "max_time_ms" has been reached. The "result" attribute is a
197 MongoDB::CommandResult object.
198 MongoDB::NetworkTimeout
200 This error is thrown when a network operation exceeds a timeout,
202 typically "connect_timeout_ms" or "socket_timeout_ms".
203 MongoDB::UsageError
205 Indicates invalid arguments or configuration options. Not all usage
206 errors will throw this — only ones originating directly from the
207 MongoDB::* library files. Some type and usage errors will originate
208 from the Type::Tiny library if the objects are used incorrectly.
209 Also used to indicate usage errors for transaction commands.
211
213 The following error code constants are automatically exported by this
214 module.
215 BAD_VALUE => 2,
217 UNKNOWN_ERROR => 8,
218 NAMESPACE_NOT_FOUND => 26,
219 EXCEEDED_TIME_LIMIT => 50,
220 COMMAND_NOT_FOUND => 59,
221 WRITE_CONCERN_ERROR => 64,
222 NOT_MASTER => 10107,
223 DUPLICATE_KEY => 11000,
224 DUPLICATE_KEY_UPDATE => 11001, # legacy before 2.6
225 DUPLICATE_KEY_CAPPED => 12582, # legacy before 2.6
226 UNRECOGNIZED_COMMAND => 13390, # mongos error before 2.4
227 NOT_MASTER_NO_SLAVE_OK => 13435,
228 NOT_MASTER_OR_SECONDARY => 13436,
229 CANT_OPEN_DB_IN_READ_LOCK => 15927,
230 This is a very, very small subset of error codes possible from the
232 server, but covers some of the more common ones seen by drivers.
233 Note:
235 · Only "MongoDB::DatabaseError" objects have a "code" attribute.
237 · The database uses multiple write concern error codes. The driver
239 maps them all to WRITE_CONCERN_ERROR for consistency and
240 convenience.
241
243 From MongoDB 4.0 onwards, errors may contain an error labels field.
244 This field is populated for extra information from either the server or
245 the driver, depending on the error.
246 Known error labels include (but are not limited to):
248 · "TransientTransactionError" - added when network errors are
250 encountered inside a transaction.
251 · "UnknownTransactionCommitResult" - added when a transaction commit
253 may not have been able to satisfy the provided write concern.
