TypeScript: Kiota.Builder.KiotaBuilder[0]: error generating the client: the current dom node already contains a child with name

[NikolayLS]

Hello!

I'm trying to generate a TypeScript API client for the following OpenApi specification:

https://vdc-download.vmware.com/vmwb-repository/dcr-public/57e38985-f93c-4dba-baaf-cc7a8f77664e/ad079dcd-ef86-4be5-8e82-5dee43c79e74/vi_json_openapi_specification_v8_0_2_0.zip

I have installed "kiota" and followed the instructions.

./kiota --version
1.12.0+1735a2ff916ebec661974d9560f1dd00d3dc349b

And this is the problem that I'm hitting:

crit: Kiota.Builder.KiotaBuilder[0]
      error generating the client: the current dom node already contains a child with name HostScsiTopologyInterface and of type CodeClass

Note: I can successfully generate API clients for Java/Python.

Sorry if the topic is already covered by another issue.

Hi @NikolayLS
Thanks for using kiota and for reaching out.
Can you generate again, passing --ll information and upload the full kiota log here please?

[NikolayLS]

@baywet Thanks for the prompt response!

Here is the full kiota log:

      error generating the client: the current dom node already contains a child with name HostScsiTopologyInterface and of type CodeClass

[andrueastman]

The issue here is caused byt the openApi description contains the type HostScsiTopology and HostScsiTopologyInterface. When the refiner is creating the interface for HostScsiTopology by appending the Interface suffix, there is a collision in the names between interface to be created and the existing model HostScsiTopologyInterface.

Solution here is to have the refiner check the new interface name exists in the namespace and try to disambiguate further before trying to add it in the refiner.

kiota/src/Kiota.Builder/Refiners/TypeScriptRefiner.cs

Line 955 in bf97766

var temporaryInterfaceName = interfaceNamingCallback.Invoke(modelClass);

@NikolayLS Any chance this is something you'd be willing to submit a PR for?
