VertexAi depending ktor 2, time to update?

[Curwe]

[REQUIRED] Step 2: Describe your environment

• Android Studio version: Meerkat Feature Drop Canary 7

• Firebase Component: BOM, Crashlytics, Config, Messaging, Analytics and Vertexai

• Component version: 33.10.0

• Ktor version 3.1.1

• Coil 3.1.0

[REQUIRED] Step 3: Describe the problem

Vertexai sdk is depending on a older version of ktor 2. And it makes apps running ktor 3 struggling.
I did read this on this closed issue #6413 that ktor 3 was to new and you want to wait, it's been a while now so I'll raise this issue again.

Steps to reproduce:

You can run the app with ktor 3 enabled. But as soon as I call generativeModel.startChat() the client crash with Caused by: java.lang.ClassNotFoundException: Didn't find class "io.ktor.client.plugins.HttpTimeout"

Hope this can be fixed in a soon rather then later release.
Cheers.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @Curwe, thank you for reaching out. As mentioned in the comment here, upgrading a project to Ktor 3.0.0, will cause breaking changes because it will be a project level upgrade.

We understand that Ktor 3.x.x will resolve the issue "NoClassDefFoundError of HTTPTimeoutCapability. I’ll bring it up to our engineers and see what we can do here.

I'll go ahead and mark this as a feature request. While we are unable to promise any timeline for this, we'll definitely keep this under our radar.

P.S. For folks who find this useful, adding an emoji thumbs up on the original post can help us prioritize adding this to the roadmap.

Thanks, happy about that :)

Hello, I completely confirm this request. More and more libraries are now using Ktor 3, and therefore we cannot use this dependency without this update.

I really wanted to use this library, but i cannot because of this issue, is there any temporal workaround?

Only workaround I've seen so far is pulling the entire firebase lib, updating the ktor version yourself, but that's a lot tbh..

Or downgrade to ktor2, with coil2 if you use coil. But then you would lose some extras, like coil2 not supporting fetching SVGs.
