Critical error generating HTTP

[mikekistler]

What are you generating using Kiota, clients or plugins?

API Client/SDK

In what context or format are you using Kiota?

Nuget tool

Client library/SDK language

None

Describe the bug

I am trying to generate HTTP snippets for the Catalog.API in eShop. Here's what happens

>kiota generate --openapi src/Catalog.API/Catalog.API_v2.json --language HTTP --output src/Catalog.API/HTTP
crit: Kiota.Builder.KiotaBuilder[0]
      error generating the client: An item with the same key has already been added. Key: api%2Dversion

Not sure what it's complaining about here, but api-version is a parameter on every operation.

Expected behavior

The API description is valid (no errors reported by Spectral validator) so I would expect no critical errors from Kiota.

I would also expect much better information about the error. The message displayed by Kiota gives me no clue about why this is a problem or how I would fix it.

How to reproduce

Clone the eShop repo and run the kiota command I showed above from the root of the repo.

Open API description file

Catalog.API_v2.json

Kiota Version

1.24.0+938d45efe40350345da733b1025af0cdaf31eea7

Hey @mikekistler, you need to pass --clean-output as an argument. Seems like there's already a client in your output directory

[mikekistler]

@Onokaev I tried adding --clean-output but I'm getting the same error:

>kiota generate --openapi src/Catalog.API/Catalog.API_v2.json --language HTTP --output src/Catalog.API/Catalog.API.generated.http --clean-output
A newer version of Kiota (1.24.1) is available. You are currently using version 1.24.0. https://aka.ms/get/kiota

Can you try to delete any files that might exist in src/Catalog.API/Catalog.API.generated.http and try to run the command again and see if you are getting any errors?

[mikekistler]

Same result:

>rm -rf src/Catalog.API/Catalog.API.generated.http 
>ls src/Catalog.API/Catalog.API.generated.http 
ls: src/Catalog.API/Catalog.API.generated.http: No such file or directory
>kiota generate --openapi src/Catalog.API/Catalog.API_v2.json --language HTTP --output src/Catalog.API/Catalog.API.generated.http --clean-output

There's a bug with the generation. We'll fix it and share an update here.
Apologies for the inconvenience
