I'm trying to build a chatbot using Amazon's boto3 library. Right now, I am trying to create an intent using the put_intent function. My code is as follows:

intent = lexClient.put_intent(name = 'test',                                 
                              sampleUtterances = ["Who is messi?"]  
                              )

When I try running this, I get the following exception:

botocore.errorfactory.BadRequestException: An error occurred (BadRequestException) when calling the PutIntent operation: RelativeId does not match Lex ARN format: intent:test2:$LATEST

Can anyone tell me what I'm doing wrong?

TT.

I got the same error when trying to have a digit in intent name field. Realized that was not allowed when trying to do the same from AWS console.

Error handling could really be more specific.

    This is the correct answer. Bots, Intents, and Slot types can only have letters and non-consecutive underscores. – eczajk Jun 29 '19 at 02:52

Try taking the question mark out of the utterance, that has caused me issues in the past!

  • That was the problem. Thank you so much!! – dinod7 Jul 13 '17 at 13:21

    No worries! Would you mind marking the answer as correct? It does seem a bit bizarre that the character which breaks utterances is the question mark character! – Dave Kerr Jul 14 '17 at 03:22

You need to run GetSlotType. That will return current checksum for that slot. Put that checksum in your PutSlotType checksum. Big bang boom.

https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/LexModelBuildingService.html#getSlotType-property

var params = { name: "AppointmentTypeValue", checksum:'54c6ab5f-fe30-483a-a364-b76e32f6f05d',

description: "Type of dentist appointment to schedule'",
enumerationValues: [
    {
        value: "cleaning"
    },
    {
        value: "whitening"
    },
    {
        value: "root canal"
    },
    {
        value:"punch my face"
    }
]

};

For the put_intent function I faced similar issues. At least the following 3 are worth mentioning.

  1. Sample Utterances

There are requirements for the sample utterances:

An utterance can consist only of Unicode characters, spaces, and valid punctuation marks. Valid punctuation marks are: periods for abbreviations, underscores, apostrophes, and hyphens. If there is a slot placeholder in your utterance, ensure that it's in the {slotName} format and has spaces at both ends.

It seems like there is no error raised when calling the put_intent function with the following code.

intent = lexClient.put_intent(name = 'test',                                 
                              sampleUtterances = ["Who is messi"]  
                              )

However, if you try to add it to your bot and start building the bot it will fail.

To fix it remove the question mark at the end of you sampleUtterance.

intent = lexClient.put_intent(name = 'test',                                 
                              sampleUtterances = ["Who is messi?"]  
                              )
  1. Prior intent version

If your intent already exists you need to add the checksum to your function call. To get the checksum of your intent you can use the get_intent function.

For example docs:

response = client.get_intent(
    name='test',
    version='$LATEST'
)
found_checksum = response.get('checksum')

After that you can put a new version of the intent:

intent = lexClient.put_intent(name = 'test',                                 
                              sampleUtterances = ["Who is messi"],
                              checksum = found_checksum
                              )
  1. Intent Name (correct in your case, just adding this for reference)

It seems like the name can only contain letters, underscores, and should be <=100 in length. Haven't found anything in the docs. This is just trial and error. Calling put_intent with the following:

intent = lexClient.put_intent(name = 'test_1',                                 
                              sampleUtterances = ["Who is messi"]  
                              )

Results in the following error:

BadRequestException: An error occurred (BadRequestException) when calling the PutIntent operation: RelativeId does not match Lex ARN format: intent:test_1:$LATEST

To fix the name you can replace it to:

intent = lexClient.put_intent(name = 'test',                                 
                              sampleUtterances = ["Who is messi"]  
                              )
