App fails after adding a new endpoint

[tbi88]

Hi

I have a custom OpenAPI app which was working just fine. This morning I have added an additional action to it. The version got changed from 1.0.0 to 1.1.0. When I active the new version in a workflow, the app fails. Also it would be cool if we could just choose the version of an OpenAPI app in the GUI like with the custom apps.

{"success":false,"reason":"An exception occurred while running this function. See exception for more details and contact support if this persists (support@shuffler.io)","exception":"'Vectra3596be88ff136d1a90ca7e6db7e7c30e' object has no attribute 'prepare_response'"}

Even when I deleted the new action, it still fails. Do you have any idea what could be the cause here?

Also I am wondering regarding the version system of these apps. I would expect, that the version is changing with every change I make. But this seems not to be the case here. Changed it multiple times today, still on version 1.1.0. Can I somehow force a version change?

Currently running version 1.1.0 of Shuffle, maybe the version is coming from that?

And here is the app if that helps.

Hey! Could you share the OpenAPI/swagger for it as well? This will help with the code generation problems :)

Not sure if I have that. I have created the app from scratch. Maybe my initial information was somehow misleading regarding this.

You can download the specification from the /apps screen! When making from scratch, it still becomes exportable :)

Alright, but that is the same file I have already provided (vectra.yaml) as a ZIP file.

My bad, I thought that was the entire app. Testing it all now :+1:

@tbi88 quick update:

• It seems to run in our lab. On closer inspection, did you update the App SDK on the server? The SDK contains the "prepare_response" function. Quick way to download it:

  docker pull frikky/shuffle:app_sdk

  After downloaded, rebuild the app again.

• The versions are static numbers for now, but which will be changable in the future. The reason for 1.0.0 -> 1.1.0 is because of the new structure of the response, where not changing this would've caused a lot of existing systems to stop functioning.

docker pull frikky/shuffle:app_sdk

Thank you, that fixed the issue. So this needs to be done after upgrading to a new version? Probably missed it on the worker nodes.

It's not necessary every time, but we just have it as a general recommendation, as we may have added extra utilities, bugfixes or speedups for apps there

ok good to know. thanks again.
