name^*required	string
message	string
cause	any

Properties

Name	Type	Description
cause	any

message^*required	string
name^*required	string
stack	string
prepareStackTrace	Object	Optional override for formatting stack traces
stackTraceLimit^*required	number

ApiGatewayError

Dedicated error response class for errors thrown by API Gateway. Autogenerated SDK Clients have built-in handler for API Gateway errors that throws this error.

Constructors

new ApiGatewayError(response,body)

ClientRequestError

Generic error class for service errors, used to handle both expected and unexpected service-level errors.

Interfaces

ApiGatewayErrorDetails

Reference for ApiGatewayError details object. Contains information about received API Getaway error.

Properties

Name	Type	Description
constraintViolations	Array<ConstraintViolation>	An array of ConstraintViolation object, refer to ConstraintViolation object reference for more details.
errorCode	string	String value representing a more detailed error information than the http response code alone. Must be a single word in CamelCase, and all possible values must be documented.
errorCodeProperties	Object
errorRef	string	UUID string that represents a reference of the error into e.g., the log file of the service.
missingPermissions	Array<string>	Must be an array of strings containing a complete list of missing IAM permissions necessary to successfully execute the request. Should be set if the API returns a 403 - Forbidden response in case of missing OAuth user permissions.
missingScopes	Array<string>	Must be an array of strings containing a complete list of missing IAM scopes necessary to successfully execute the request. Should be set if the API returns a 403 - Forbidden response in case of missing OAuth scopes.
traceId	string	String containing a 32-character hex integer value that is used for tracing.

CommonApiError

Common API error structure, established by Dynatrace API guidelines.

Properties

Name	Type	Description
code^*required	number	The error code should be set to the HTTP error code by default. The error code may be set to an API-specific error code which must be properly documented.
details	T	Additional details about the error may be added in a details field. Refer to CommonErrorDetails
help	string	An additional help field may be added which must be a URL to further information on how to deal with the error. This may be some detailed error documentation page or a link to the Dynatrace support system, etc.
message^*required	string	The error message should be short and precise, it should not contain details.

CommonErrorDetails

CommonApiError details object reference. Contains common API error information. This object is used to convey additional information about the error like e.g., which query parameter exactly violated a precondition.

Details may contain any fields to further describe the error

Properties

Name	Type	Description
constraintViolations	Array<ConstraintViolation>	An array of ConstraintViolation object, refer to ConstraintViolation object reference for more details.
errorCode	string	String value representing a more detailed error information than the http response code alone. Must be a single word in CamelCase, and all possible values must be documented.
errorRef	string	UUID string that represents a reference of the error into e.g., the log file of the service.
missingPermissions	Array<string>	Must be an array of strings containing a complete list of missing IAM permissions necessary to successfully execute the request. Should be set if the API returns a 403 - Forbidden response in case of missing OAuth user permissions.
missingScopes	Array<string>	Must be an array of strings containing a complete list of missing IAM scopes necessary to successfully execute the request. Should be set if the API returns a 403 - Forbidden response in case of missing OAuth scopes.
traceId	string	String containing a 32-character hex integer value that is used for tracing.

ConstraintViolation

Contains information about an input parameter (path, query or request body) that violated some validation rule of the service API and caused the warning.

May contain additional fields further describing the warning.

Properties

Name	Type	Description
message^*required	string	Mandatory field message describing the warning.
parameterLocation	string	Describes the general location of the violating parameter (query parameter, request body, etc.)
path	string	Refers to the violating parameter within the parameterLocation.

ErrorResponseBody

Basic error envelope, that enforces all error to have mandatory "error" property.

Properties

Name	Type	Description
error^*required	T	error object must have two mandatory fields (code, message) and may have two additional fields (help, details): refer to the CommonApiError for more details.
