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.

AccessDeniedException(AccessDeniedException)

You do not have sufficient access to perform this action.

DryRunOperation(DryRunOperation)

Exception raised to indicate a successfully authorized action when the DryRun flag is set to "true".

HomeRegionNotSetException(HomeRegionNotSetException)

The home region is not set. Set the home region to continue.

InternalServerError(InternalServerError)

Exception raised when an internal, configuration, or dependency error is encountered.

InvalidInputException(InvalidInputException)

Exception raised when the provided input violates a policy constraint or is entered in the wrong format or data type.

PolicyErrorException(PolicyErrorException)

Exception raised when there are problems accessing Application Discovery Service (Application Discovery Service); most likely due to a misconfigured policy or the migrationhub-discovery role is missing or not configured correctly.

ResourceNotFoundException(ResourceNotFoundException)

Exception raised when the request references a resource (Application Discovery Service configuration, update stream, migration task, etc.) that does not exist in Application Discovery Service (Application Discovery Service) or in Migration Hub's repository.

ServiceUnavailableException(ServiceUnavailableException)

Exception raised when there is an internal, configuration, or dependency error encountered.

ThrottlingException(ThrottlingException)

The request was denied due to request throttling.

UnauthorizedOperation(UnauthorizedOperation)

Exception raised to indicate a request was not authorized when the DryRun flag is set to "true".

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).
