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.

ConcurrentModificationException(ConcurrentModificationException)

Thrown if there are parallel requests to modify a resource.

DeveloperUserAlreadyRegisteredException(DeveloperUserAlreadyRegisteredException)

The provided developer user identifier is already registered with Cognito under a different identity ID.

ExternalServiceException(ExternalServiceException)

An exception thrown when a dependent service such as Facebook or Twitter is not responding

InternalErrorException(InternalErrorException)

Thrown when the service encounters an error during processing the request.

InvalidIdentityPoolConfigurationException(InvalidIdentityPoolConfigurationException)

If you provided authentication information in the request, the identity pool has no authenticated role configured, or STS returned an error response to the request to assume the authenticated role from the identity pool. If you provided no authentication information in the request, the identity pool has no unauthenticated role configured, or STS returned an error response to the request to assume the unauthenticated role from the identity pool.

Your role trust policy must grant AssumeRoleWithWebIdentity permissions to cognito-identity.amazonaws.com.

InvalidParameterException(InvalidParameterException)

Thrown for missing or bad input parameter(s).

LimitExceededException(LimitExceededException)

Thrown when the total number of user pools has exceeded a preset limit.

NotAuthorizedException(NotAuthorizedException)

Thrown when a user is not authorized to access the requested resource.

ResourceConflictException(ResourceConflictException)

Thrown when a user tries to use a login which is already linked to another account.

ResourceNotFoundException(ResourceNotFoundException)

Thrown when the requested resource (for example, a dataset or record) does not exist.

TooManyRequestsException(TooManyRequestsException)

Thrown when a request is throttled.

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).
