All possible error types for this service.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DefaultUndefinedFault(DefaultUndefinedFault)

The StartWorkflowExecution API action was called without the required parameters set.

Some workflow execution parameters, such as the decision taskList, must be set to start the execution. However, these parameters might have been set as defaults when the workflow type was registered. In this case, you can omit these parameters from the StartWorkflowExecution call and Amazon SWF uses the values defined in the workflow type.

If these parameters aren't set and no default parameters were defined in the workflow type, this error is displayed.

DomainAlreadyExistsFault(DomainAlreadyExistsFault)

Returned if the domain already exists. You may get this fault if you are registering a domain that is either already registered or deprecated, or if you undeprecate a domain that is currently registered.

DomainDeprecatedFault(DomainDeprecatedFault)

Returned when the specified domain has been deprecated.

LimitExceededFault(LimitExceededFault)

Returned by any operation if a system imposed limitation has been reached. To address this fault you should either clean up unused resources or increase the limit by contacting AWS.

OperationNotPermittedFault(OperationNotPermittedFault)

Returned when the caller doesn't have sufficient permissions to invoke the action.

TooManyTagsFault(TooManyTagsFault)

You've exceeded the number of tags allowed for a domain.

TypeAlreadyExistsFault(TypeAlreadyExistsFault)

Returned if the type already exists in the specified domain. You may get this fault if you are registering a type that is either already registered or deprecated, or if you undeprecate a type that is currently registered.

TypeDeprecatedFault(TypeDeprecatedFault)

Returned when the specified activity or workflow type was already deprecated.

TypeNotDeprecatedFault(TypeNotDeprecatedFault)

Returned when the resource type has not been deprecated.

UnknownResourceFault(UnknownResourceFault)

Returned when the named resource cannot be found with in the scope of this operation (region or domain). This could happen if the named resource was never created or is no longer available for this operation.

WorkflowExecutionAlreadyStartedFault(WorkflowExecutionAlreadyStartedFault)

Returned by StartWorkflowExecution when an open execution with the same workflowId is already running in the specified domain.

Unhandled(Unhandled)

👎Deprecated: Matching Unhandled directly is not forwards compatible. Instead, match using a variable wildcard pattern and check .code():    err if err.code() == Some("SpecificExceptionCode") => { /* handle the error */ } See ProvideErrorMetadata for what information is available for the error.

An unexpected error occurred (e.g., invalid JSON returned by the service or an unknown error code).
