"Duplicate object name" in LUIS Programmatic API

Question

I am trying to use LUIS Programmatic API in order to create a LUIS app.

The response I get is:

"error": {
  "code": "BadArgument",
  "message": "Duplicate object name"
}

The app contains intents, utterances and several Closed Lists.

I checked that there are no utterances and no duplicate entries in closed lists, but that didn't help.

What else could cause the problem? Normally, with some other data, I was able to create the LUIS app using the same code successfully.

Answer 1

Do you have 2 or more methods in your Luis dialog that have the same intent mapped to it?

Make sure that your intents are mapped correctly. I think if you have a typo in your intent, that may map to none.

Answer 2

The problem turned out to be two entity synonyms that had different value (different, but similar Chinese characters) that for some reason were treated as the same character by LUIS.
