All possible error types for this service.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

BadGatewayException(BadGatewayException)

Either the Amazon Lex bot is still building, or one of the dependent services (Amazon Polly, AWS Lambda) failed with an internal service error.

§

BadRequestException(BadRequestException)

Request validation failed, there is no usable message in the context, or the bot build failed, is still in progress, or contains unbuilt changes.

§

ConflictException(ConflictException)

Two clients are using the same AWS account, Amazon Lex bot, and user ID.

§

DependencyFailedException(DependencyFailedException)

One of the dependencies, such as AWS Lambda or Amazon Polly, threw an exception. For example,

  • If Amazon Lex does not have sufficient permissions to call a Lambda function.

  • If a Lambda function takes longer than 30 seconds to execute.

  • If a fulfillment Lambda function returns a Delegate dialog action without removing any slot values.

§

InternalFailureException(InternalFailureException)

Internal service error. Retry the call.

§

LimitExceededException(LimitExceededException)

Exceeded a limit.

§

LoopDetectedException(LoopDetectedException)

This exception is not used.

§

NotAcceptableException(NotAcceptableException)

The accept header in the request does not have a valid value.

§

NotFoundException(NotFoundException)

The resource (such as the Amazon Lex bot or an alias) that is referred to is not found.

§

RequestTimeoutException(RequestTimeoutException)

The input speech is too long.

§

UnsupportedMediaTypeException(UnsupportedMediaTypeException)

The Content-Type header (PostContent API) has an invalid value.

§

Unhandled(Unhandled)

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

When logging an error from the SDK, it is recommended that you either wrap the error in DisplayErrorContext, use another error reporter library that visits the error’s cause/source chain, or call Error::source for more details about the underlying cause.
