How can I catch the exception when I use OpenAI API client for Kotlin?

I use OpenAI API client for Kotlin in my Android Studio project.

I use Code A to transcribe a voice to text

1: I don't know if val transcription = openAI.transcription(transcriptionRequest) can throw exception, could you tell me?

2: How can I get the error informatioin when val transcription = openAI.transcription(transcriptionRequest) crashed ?

BTW, the Code B is source code, It returns Transcription class, and it seems not to throw exception.

Code A

  val apiKey = "sk-..."
    val openAI = OpenAI(apiKey)

    val transcriptionRequest = TranscriptionRequest(
        audio = FileSource(path = mInfo.soundFilename.toPath(), fileSystem = FileSystem.SYSTEM),
        model = ModelId("whisper-1"),
    )

   val transcription = openAI.transcription(transcriptionRequest)

    mInfo.text = transcription.text

Code B

  @BetaOpenAI
    public suspend fun transcription(request: TranscriptionRequest): Transcription

Looking at aallam/openai-kotlin issue 131, you can try and encapsulate your OpenAI code with the exceptions from the com.aallam.openai.api.exception package:

val apiKey = "sk-..."
val openAI = OpenAI(apiKey)

val transcriptionRequest = TranscriptionRequest(
    audio = FileSource(path = mInfo.soundFilename.toPath(), fileSystem = FileSystem.SYSTEM),
    model = ModelId("whisper-1"),
)

try {
    val transcription = openAI.transcription(transcriptionRequest)
    mInfo.text = transcription.text
} catch (e: OpenAIException) {
    // Handle OpenAIExceptions
    println("OpenAIException: ${e.message}")
} catch (e: OpenAIHttpException) {
    // Handle OpenAIHttpExceptions
    println("OpenAIHttpException: ${e.message}")
} catch (e: OpenAIAPIException) {
    // Handle OpenAIAPIExceptions
    println("OpenAIAPIException: ${e.message}")
} catch (e: Exception) {
    // Handle any other exceptions
    println("Unexpected error: ${e.message}")
}

That would handle the specific exceptions OpenAIException, OpenAIHttpException, and OpenAIAPIException that may be thrown by the OpenAI Kotlin API client, in addition to a generic catch-all for any other exceptions.

Note that, if you are getting an empty error message, that would typically mean that the Exception itself is being thrown, but no specific message has been assigned to it.
In this case, it would appear that the OpenAI Kotlin client library is not assigning a message to the exception that it throws when the API key is invalid.

You might get more information by calling e.toString() instead of e.message in your catch blocks, as toString() typically includes both the exception class name and the message, while e.message only provides the message.
However, if the library does not provide a message, e.toString() might not provide much more information.

That would be:

val apiKey = "sk-..."
val openAI = OpenAI(apiKey)

val transcriptionRequest = TranscriptionRequest(
    audio = FileSource(path = mInfo.soundFilename.toPath(), fileSystem = FileSystem.SYSTEM),
    model = ModelId("whisper-1"),
)

try {
    val transcription = openAI.transcription(transcriptionRequest)
    mInfo.text = transcription.text
} catch (e: OpenAIException) {
    // Handle OpenAIExceptions
    println("OpenAIException: ${e.toString()}")
} catch (e: OpenAIHttpException) {
    // Handle OpenAIHttpExceptions
    println("OpenAIHttpException: ${e.toString()}")
} catch (e: OpenAIAPIException) {
    // Handle OpenAIAPIExceptions
    println("OpenAIAPIException: ${e.toString()}")
} catch (e: Exception) {
    // Handle any other exceptions
    println("Unexpected error: ${e.toString()}")
}
